No District line through Chiswick on 10 and 11 October. National Highways has finished the M4 pillar repairs early and is lifting the A4 lane closure.

Chiswick roadworks are rarely Chiswick’s own. Driving here means dealing with three separate highway authorities on a journey of two miles, and the first thing to understand is which one owns the tarmac you are stuck on. Hounslow Council is responsible for the residential streets, but not the A4 outside your window, and not the motorway above it. That split is why “who do I report this to” is genuinely confusing here, and it is why the two things most likely to hold you up this month were not decided by your council at all.

What is shut in Chiswick right now

Checked against National Highways, Transport for London and Hounslow Council’s own traffic notices on Sunday 4 October 2026:

  • The M4 pillar repairs above the A4 are finished, six weeks early. National Highways’ update of 24 September 2026 says all 12 pillars are done “ahead of schedule”. The job had been due to run to 7 November. It says it is now removing the scaffolding and “taking out the lane closure on the A4 westbound” near Capital Interchange Way, which has been shut since March.
  • The overnight A4 closures to clear the site have run. The A4 Great West Road was closed in both directions between Ealing Road and the Chiswick Roundabout from 10pm to 5.30am for four nights, 29 September to 2 October. National Highways has not published a date on which every barrier will be gone, so treat the westbound lane as returning rather than returned until you have driven it.
  • No M4 or A4 closures near Chiswick in the coming week. National Highways’ closure report, last updated on 2 October and running to Thursday 8 October, lists nothing on the M4 between junctions 1 and 3 and nothing on the A4. The nearest entry is a link road closure between M4 junction 4B and the M25 at Heathrow on the night of 8 October, about eight miles west. The report covers full closures only, so lane closures that leave the road open do not appear in it.
  • Nothing on the red routes through Chiswick. TfL’s road disruption data, read on 4 October 2026, carried no works on the A4, the A316 or the A205 between the Chiswick Roundabout and the Hogarth roundabout.
  • The only TfL-listed works in the borough are still in Feltham, and they have been extended. Temporary signals for Cadent gas works on Hatton Road at the junction with Myrtle Avenue, TW14, were due to end on 28 September. TfL now lists them until 13 November. Feltham is about ten miles west of Chiswick.
  • Hammersmith Bridge remains closed to motor traffic, as it has been since April 2019. See below.

Next weekend: no District line through Chiswick on 10 and 11 October

The rail closures matter more than the roads this month. From Transport for London’s own line status, read on 4 October 2026:

  • Saturday 10 and Sunday 11 October: no District line service between Edgware Road or Tower Hill and Ealing Broadway, Kensington (Olympia), Richmond and Wimbledon. That takes in Turnham Green, Chiswick Park, Stamford Brook and Gunnersbury. Replacement buses run.
  • TfL’s advice that weekend is to use Mildmay line trains between Gunnersbury, Kew Gardens and Richmond.
  • The Piccadilly line has no closure listed for 10 and 11 October.
  • The following weekend, 17 and 18 October, it is worse. The District is shut between Turnham Green and Ealing Broadway, and the Piccadilly has no service between Hammersmith and Heathrow or Uxbridge from 1am on Saturday 17 October and all day Sunday 18 October, including the Night Tube. Replacement buses run on both. TfL is sending Heathrow passengers to the Elizabeth line, which runs a reduced service to Heathrow on the Sunday.
  • Chiswick station, on the South Western Railway Hounslow loop, has nothing listed. TfL’s disruption feeds for Chiswick, Turnham Green, Chiswick Park and Gunnersbury were empty on 4 October 2026.

Check TfL’s status page on the morning rather than the week before. Weekend closures are moved and cancelled.

Hammersmith Bridge: closed to cars, and now bidding to stay open at all

The bridge has been closed to motor traffic since April 2019. Pedestrians and cyclists got the main carriageway back in April 2025 once the cracked pedestals had been stabilised. The open question since then has been whether cars and buses would ever return, and in July 2026 that question was answered.

Hammersmith and Fulham’s cabinet met on 6 July 2026 and formalised the decision not to reopen the bridge to motor traffic, on the strength of its own Report to Cabinet on the Hammersmith Bridge Restoration Programme published the same day. The report concluded there is “no financial option available” to make the 139-year-old Grade II listed structure strong enough for modern vehicles. Doing it properly would mean building an entirely new bridge inside the heritage casing, at a projected £300 million* (New Civil Engineer, 8 July 2026).

The funding is what killed it. Government had required the Department for Transport, Transport for London and the borough to cover a third each, and Hammersmith and Fulham had planned to borrow its £100 million share and repay it through a toll on drivers using the bridge. With no vehicle restoration, there is no toll to levy and no way to service the borrowing. The £1 billion Structures Fund was no use for that job either, because it requires construction to be finished by 31 March 2030, which is not a realistic timetable for a full vehicle restoration.

The August development: the council has now submitted a Structures Fund bid for the scaled-down phase 2 instead, and published the submission on 4 August 2026. It sets out a £128.05 million programme of critical repairs and strengthening, with construction starting mid-April 2027 and finishing by mid-March 2030. The reason for the hurry is in the bid itself: the bridge is open to pedestrians and cyclists on a temporary basis under a CS 470 risk assessment that is only valid until March 2027, and the council writes that without further intervention it is “highly likely” the bridge will close to active travel users and to river traffic below (Hammersmith and Fulham Structures Fund submission).

What that means from Chiswick: the short hop across to Barnes and Castelnau is a walking and cycling route for the foreseeable future, and even that is not guaranteed past March 2027 until the funding lands. Every car journey to that side of the river uses Chiswick Bridge, Kew Bridge or Putney Bridge, and it is worth planning around rather than discovering at the approach.

Transport for London runs the A4 Great West Road through the Hogarth roundabout, the A316 south over Chiswick Bridge, the A205 South Circular over Kew Bridge and the A406 North Circular. Hounslow Council, through its contractor Hounslow Highways, runs the borough streets including Chiswick High Road, Turnham Green Terrace and Devonshire Road.

The A4, the A316 and the A205 are Transport for London's. The streets off them are the council's. Reporting a fault to the wrong one is the commonest reason nothing happens.

The M4 viaduct: this year’s job is finished, the next one starts in 2027

The job that held up the A4 for most of 2026 is over. National Highways began refurbishing the reinforced concrete pillars that carry the M4 elevated section above the A4 Great West Road on Monday 9 March 2026, with an anticipated completion date of Saturday 7 November 2026. Twelve pillars were repaired, on top of thirteen already done since 2023.

On 24 September 2026 National Highways said it had finished “ahead of schedule”. What followed, and what it means for you:

  • The westbound lane closure near Capital Interchange Way is coming out. It had been in place 24 hours a day since March, with steel barriers between the work and the traffic.
  • Four overnight closures cleared the site. The A4 was shut in both directions between Ealing Road and the Chiswick Roundabout, 10pm to 5.30am, from 29 September to 2 October. The signed diversion was the B455 Ealing Road, then the A315 High Street, rejoining the A4 at Chiswick High Road. Buses were escorted through.
  • More work is coming. National Highways says it will “keep working on the M4 elevated section over the next few years” and that, subject to approval, it will start work at the eastern end from spring 2027. The elevated section runs west from the Chiswick Roundabout, so the eastern end is the Chiswick end. No dates or lane arrangements have been published.

Updates are posted on National Highways’ scheme page. Its weekly closure report is the place to look for one-off overnight M4 closures, which do not appear on the scheme page at all.

Who to report what to

This is the practical half of the page, because most road problems in Chiswick are small ones that go unfixed for months while people report them to the wrong body.

  • Potholes, broken street lights, blocked gullies, fly-tipping and street cleansing on borough roads: Hounslow Highways, the council’s contractor. Its published service standards are worth quoting back at it: potholes inspected within two working days and repaired between one hour for an emergency and 28 days, stretching to 56 days if traffic management is needed; illegally dumped waste removed within 24 hours; offensive graffiti removed within 24 hours and other graffiti within seven days.
  • Anything on the A4, A205, A316 or A406: those are Transport for London’s red routes, not the council’s. TfL publishes a live traffic status page for them.
  • The M4: National Highways. The motorway begins at the Chiswick Roundabout and runs west on the elevated section above the A4 over Brentford’s Golden Mile, so a good deal of what you can see from Chiswick is not London’s road at all.

Where to check what is shut right now

Hounslow does not publish a plain list of current closures, which is the single most common complaint about its roads pages. What it does publish is better than a list once you know where it is:

  • The council’s traffic notices map shows every traffic management order and temporary restriction in the borough on a map, which is the closest thing to a live picture of what is changing on the street. It is offline until the end of October, see below.
  • The council’s traffic notices page lists the same orders as documents, by month and reference number, and is where consultations appear before they take effect. This is the one that stays up.
  • TfL’s traffic status page covers the A4, the A316, the A205 and the A406.

The map is offline until the end of October

Hounslow has put a notice on its own traffic notices page saying that it is “introducing a new mapping system for permanent TMOs” and that during the changeover “the current mapping system will be unavailable for a short period, from the end of September 2026 until the end of October 2026”. The council adds that all current permanent orders will still be on the traffic notices webpage while the map is down.

The reason is worth knowing, because it also explains the flood of consolidation orders Chiswick has had all year. The council says it has been “updating and consolidating its permanent Traffic Management Orders (TMOs) to prepare for the Government’s new Digital Traffic Regulation Order (D-TRO) service”, the national system that is meant to put every traffic order into one machine-readable database. Every one of those Chiswick zone consolidations that changed nothing on the street was part of getting ready for it.

For the next month, then: if you want to know what restriction applies to a particular kerb, the map will not answer it, and the answer is in the PDFs on the traffic notices page.

Parking and speed limits: what is open for objection, and when it shuts

Most of Chiswick sits inside a controlled parking zone, and the council has spent 2026 consolidating and amending several of them at once. Objections go to trafficorders@hounslow.gov.uk, and they only count if you quote the reference printed inside the notice, which is not always the one on the index page.

Five notices are open on 4 October, and four of them name Chiswick streets. Three were deposited on Friday 2 October, and all three close on 23 October 2026.

  • Duke’s Avenue, outside No. 88: a length of permit parking would go (reference TMO/P054/26). The council proposes to revoke part of the permit parking place on the north-east side outside No. 88 for a new crossover, and put in a no waiting restriction there, Monday to Friday 9.30am to 12.30pm and 4.30pm to 6.30pm, and Saturdays 9.30am to 12.30pm. It amends the Central Chiswick parking zone order. Objections by 23 October.
  • Two new electric vehicle charging places in Chiswick (reference TMO/P052/26). One would be on Silver Crescent, on the north-east side, 11 metres long, starting 7 metres north of the southern wall of 596 Chiswick High Road. The other would be on Upham Park Road, on the west side, 11 metres long, starting 6 metres south of No. 1a. Both would be electric-vehicle-only at all times, and existing bays would be adjusted to fit them. The same notice adds charging places on Bethany Waye in Feltham, and on Strafford Road and Wheatlands in Hounslow. It amends the West Chiswick and East Chiswick zone orders. Objections by 23 October.
  • Osterley “people friendly streets”, in Isleworth (reference TMO/P043/26), about three miles west of Chiswick. It would bring in no left turns from 7am to 10am on weekdays on Borough Road, Musgrave Road and Northumberland Avenue, a speed table on Osterley Road near Thornbury Court, speed cushions on Osterley Road between the Great West Road and Meadowbank Close, and speed cushions on Thornbury Road between Thornbury Avenue and Moreton Avenue. It also takes out a 6 metre parking place on The Grove. Objections by 23 October.
  • Acton Lane, outside Chiswick Terrace: the council proposes to stop up 55 square metres of footway (reference SUO39). This is not a parking order but a stopping up of highway under section 247 of the Town and Country Planning Act 1990, which permanently removes a strip of public footway. It runs approximately 38.3 metres along Acton Lane and varies in width between about 1.441 and 3.65 metres. It is to allow planning permission P/2024/4316, for a six-storey building containing an 85-bed residential specialist care facility and one commercial unit, after demolition of the existing buildings at 1-15 Acton Lane, W4 5LY. Objections are due within 28 days from 25 September 2026, which is 23 October, quoting “Acton Lane / Chiswick Terrace Stopping Up Order 2026”.
  • Disabled parking places, reference TMO/P051/26. Objections close on Friday 9 October 2026. In Chiswick it would create a new disabled bay at 211 Staveley Gardens and revoke the disabled parking permit place at 43 Beverley Court, Wellesley Road (permit D115). It also creates or changes bays in Brentford, Heston, Isleworth, Feltham and Hounslow.

Two have closed. Objections to the Chiswick Lane South electric vehicle charging place (TMO/P050/26) and to the waiting and loading changes at Burnaby Gardens and Heathfield Terrace (TMO/P046/26) closed on 2 October. Neither has a decision yet.

One decision has landed, and it is the Brentford one. The High Street, Brentford changes, reference TMO/P049/26, were made on 23 September 2026 and come into operation on 25 September. The effect:

  • five pay and park bays are revoked: two on High Street, two on Catherine Wheel Road and one on Brent Way
  • two new pay and park bays are introduced on High Street, both maximum stay two hours, Monday to Saturday 8am to 6.30pm
  • a new no waiting and no loading restriction, 7am to 10am and 4.30pm to 6.30pm, applies on the north-west side outside Nos. 1-30 House, High Street

That is the one-hour to two-hour switch we flagged when it was still a proposal. Anyone who wants to question the order’s validity in the High Court has six weeks from 23 September, which runs out on 4 November 2026.

Four outcomes are still unpublished, and they are now overdue rather than pending:

  • Chiswick Riverside, TMO/P045/26. Objections closed on 4 September. A month later, on 4 October, there is still no notice of making. It would raise the maximum stay for pay by phone users from one hour to two in bays on Strand on the Green and Thames Road, and convert several permit-holders-only bays into shared-use bays.
  • Nine electric vehicle charging bays across Brentford, Hounslow and Isleworth (TMO/P044/26) and the drop from 40mph to 30mph on Bedfont Road in Feltham (quote TMO/P040/26, not the TMO-P041-26 the council’s index shows). Both closed on 11 September.
  • Alderney Avenue controlled parking zone in Heston (TMO/P047/26). Objections closed on 18 September. Heston is about five miles west of Chiswick.

Already in force and unannounced. The council made Amendment No. 5 to its disabled parking places order on 19 August 2026, in force from 21 August. In Chiswick it creates a new disabled bay at 33 Eastbury Grove, and revokes existing ones at 29 Hadley Gardens, 13 Russell Kerr Close and 92 Thornton Avenue. If you have parked in one of those three for years on a blue badge, it is no longer a bay.

Mid Chiswick is decided. The consolidation order for the zone, TMO/P029/26, was made on 26 August 2026. It revokes and reintroduces the previous order “without any material change to the substance” of the restrictions, so it restates the zone rather than changing it. The six-week window to challenge its validity in the High Court runs out on Wednesday 7 October 2026. One oddity is still uncorrected: the notice states the order “will come into force on 28 August 2025”, a year before it was made, which reads as a typing error for 2026.

The index trap. The council’s index now has an October 2026 heading, and the three notices of 2 October are filed under it. One trap is unchanged: the Chiswick Lane South electric vehicle notice is still listed twice, once as “Chiswick Lane South” and once as “Netheravon Road”, and both links open the same document covering the one location.

A notice of intent to amend the Central Chiswick CPZ (TMO-P034-26) was published in June 2026, and consolidation orders covering Central Chiswick, East Chiswick, West Chiswick, Chiswick Riverside, Chiswick Mall and the Stile Hall area were made in March 2026. All of them are on the council’s traffic notices page, filed by month.

Permit charges in Hounslow are based on your vehicle’s carbon dioxide emissions, across seven bands from 0g/km to over 226g/km, so two neighbours on the same street pay different amounts for the same kerb (Hounslow Council).

The ULEZ applies to every road in this borough

The Ultra Low Emission Zone covers all London boroughs, so there is no part of Chiswick, Brentford, Isleworth or Feltham outside it. The charge is £12.50 a day for a non-compliant vehicle and it runs 24 hours a day, every day except Christmas Day (Transport for London). Compliant vehicles pay nothing, but you have to have checked: the charge is not issued as a fine at the roadside, it turns up later.

Getting around without the car

  • The District line. Twelve trains an hour from Turnham Green towards central London, all day, except on the weekends it is shut. It is shut through Chiswick on 10 and 11 October, and between Turnham Green and Ealing Broadway on 17 and 18 October. Our Chiswick trains to London page has the times, the fares and the platform trap at Chiswick station.
  • Cycleway 9. The segregated two-way route runs from the Hammersmith direction through Chiswick and on past Kew Bridge to Watermans Park in Brentford, with the Kew Bridge to Watermans section completed in October 2023 (Transport for London).
  • Hammersmith Bridge. Still the quickest way to Barnes on foot or by bike, and the only way it will be used for years. Walking and cycling access runs on a safety assessment valid to March 2027, so it depends on the council’s funding bid landing.

Frequently asked questions

Will Hammersmith Bridge ever reopen to cars?

On current policy, no. Hammersmith and Fulham’s cabinet formalised the decision not to reopen it to motor traffic on 6 July 2026, after its own report found there was “no financial option available” for the roughly £300 million job. The council has moved to a £128.05 million phased repair plan and submitted it to the Department for Transport’s Structures Fund on 4 August 2026, aiming to start construction in mid-April 2027 and finish by mid-March 2030. That plan keeps the bridge open to pedestrians, cyclists and river traffic rather than to vehicles.

Could Hammersmith Bridge close to pedestrians as well?

The council’s own funding bid says it might. Walking and cycling access runs on a temporary CS 470 risk assessment that is valid only until March 2027, and the bid states that without further investment it is “highly likely” the bridge will close to active travel users and to river traffic below.

Who fixes potholes in Chiswick?

Hounslow Highways, on the borough’s own streets. It says it will inspect a reported pothole within two working days and repair it within 28 days, or 56 if traffic management is required. Potholes on the A4, A316, A205 or A406 are Transport for London’s, and on the M4 they are National Highways’.

What are the roadworks on the A4 in Chiswick and Brentford?

National Highways was repairing 12 concrete pillars holding up the M4 elevated section above the A4, between M4 junctions 1 and 2. The work began on 9 March 2026 and was due to finish on 7 November, but National Highways said on 24 September that it had finished ahead of schedule. It is removing the westbound lane three closure near Capital Interchange Way, and closed the A4 overnight from 29 September to 2 October to clear the site. It plans further work at the eastern, Chiswick Roundabout end of the elevated section from spring 2027, subject to approval.

What can I still object to in Hounslow this month?

Five notices are open on 4 October 2026. A disabled parking notice (TMO/P051/26) closes on 9 October and would create a bay at 211 Staveley Gardens and revoke the permit place at 43 Beverley Court, Wellesley Road. Four close on 23 October: the loss of permit parking outside 88 Duke’s Avenue (TMO/P054/26), electric vehicle charging places on Silver Crescent and Upham Park Road (TMO/P052/26), the Osterley people friendly streets scheme in Isleworth (TMO/P043/26), and the stopping up of about 55 square metres of footway on Acton Lane outside Chiswick Terrace (SUO39). Objections go to trafficorders@hounslow.gov.uk quoting the reference printed on the notice itself, not the one on the index page.

Where can I see current road closures in Hounslow?

Normally on the council’s traffic notices map at hounslow.traffweb.app, which plots every traffic order and temporary restriction in the borough. The council has said the map will be unavailable “from the end of September 2026 until the end of October 2026” while it moves to a new mapping system for the Government’s Digital Traffic Regulation Order service. While it is down, use the council’s traffic notices page, which lists the same orders as documents by month.

Do I have to pay the ULEZ charge in Chiswick?

If your vehicle does not meet the emissions standards, yes. The zone covers every London borough, so all of Chiswick is inside it, and the £12.50 daily charge applies 24 hours a day every day except Christmas Day.

Which Chiswick parking zones are changing in 2026?

Chiswick Riverside is the one with a real change on the table. A notice of intent dated 14 August 2026 (TMO/P045/26) would double the pay by phone maximum stay from one hour to two in bays on Strand on the Green and Thames Road. Objections closed on 4 September 2026 and no decision had been published by 4 October, a month later. Mid Chiswick is settled: the consolidation order TMO/P029/26 was made on 26 August 2026, and the council says it makes no material change to the restrictions. Central Chiswick had an amendment notice in June 2026 (TMO-P034-26), and consolidation orders covering Central, East and West Chiswick, Chiswick Riverside, Chiswick Mall and Stile Hall were made in March 2026.

Why do permit prices differ between neighbours?

Because Hounslow prices permits on carbon dioxide emissions across seven bands, from 0g/km to over 226g/km, rather than charging a flat rate per household.
