Which Harrow roads close in August 2026, and when will Kenton and Hatch End routes reopen

4 August 2026 marks the start of a difficult month for drivers in Harrow, with full road closures affecting residential streets across Edgware, Pinner, Hatch End, Harrow Weald, Rayners Lane, South Harrow, Kenton and Wealdstone. Most restrictions are linked to water or gas infrastructure, but their duration varies sharply: some roads will shut for several hours, while Blythwood Road in Hatch End is scheduled to remain closed from 10 August until 30 October. In Kenton, Morland Avenue is expected to reopen on 24 August after being unavailable to through traffic since 28 April. The programme also includes closures on Oakleigh Avenue, Sedgecombe Avenue, Highfield Avenue and St Johns Road, alongside continuing works on Marlborough Hill and Princes Drive, The WP Times reports.

The practical impact will extend beyond the streets named in the programme. Residential diversions can push more vehicles towards main routes, increase pressure around school, station and shopping areas, and lengthen journeys between neighbourhoods that normally sit only minutes apart. The longest restrictions are concentrated in Hatch End and Kenton, while Wealdstone faces overlapping gas and water works. Harrow Council directs residents to its roadworks information service, while current and proposed works across the capital can also be checked through Transport for London’s LondonWorks register.

The dates below are scheduled working periods and may include time for excavation, repairs, testing and reinstatement of the carriageway.

Harrow road closures in August 2026 include 20 affected streets

The published programme identifies 20 full road closures that either continue into August or begin during the month. Water works account for most of them, followed by gas works, road maintenance and telecommunications work. The closures are spread across the borough rather than focused on a single construction zone, making borough-wide journey planning more complicated.

Several restrictions were already active before August began. Bacon Lane, Cecil Park, Fontwell Close, Willowcourt Avenue, Upton Gardens, Morland Avenue, Rusland Park Road, Marlborough Hill and Princes Drive all entered the month with works under way. Gayton Road and Northwick Avenue were scheduled to reopen on 3 August, meaning they should no longer be part of the active closure list from 4 August unless works overrun.

The main August programme is:

The programme was reported from roadworks data available through one.network and the Local Democracy Reporting Service. Harrow’s official guidance states that temporary closures and upcoming restrictions can be followed through the council’s Traffic Management Order pages.

Hatch End roadworks will bring the longest August closure

The most disruptive single project is expected on Blythwood Road in Hatch End, where water works are scheduled to close the road from Monday 10 August until Friday 30 October. That is an 82-day period covering the second half of the summer, the start of the new school term and most of October. No other closure in the published August list runs for as long.

The length of the restriction suggests that the job may involve more than a short connection or emergency repair. Extended water projects can require phased excavation, replacement of underground infrastructure, pressure testing and road reinstatement before normal access returns. The published schedule does not specify the engineering scope, so residents should rely on signs placed at the site for exact access arrangements.

Marsworth Avenue will create a second closure in Hatch End from 31 August to 11 September. Its timing means the area could have two affected residential roads during the first 11 days of September, with Blythwood Road still closed throughout.

The main points for Hatch End are:

• Blythwood Road closes on 10 August and is scheduled to reopen after 30 October.
• Marsworth Avenue closes on 31 August and remains restricted until 11 September.
• Both closures are listed as water works.
• Diversions may increase traffic on neighbouring residential streets and routes towards local stations.
• September school journeys could be affected by both projects.

Blythwood Road is the only closure in the August programme scheduled to continue through the whole of September and most of October.

Drivers using the area regularly should check the live roadworks map before leaving rather than depend on a single routine diversion. Temporary traffic management can change during different phases of a project, particularly where contractors need to preserve access for residents, emergency vehicles or deliveries.

Kenton closures affect four roads before Morland Avenue reopens

Kenton has the largest concentration of closures in the published list. Five streets are affected during August, although the dates do not overlap for the entire month. Willowcourt Avenue and Upton Gardens are due to remain closed until 10 August, Sedgecombe Avenue closes from 6 to 28 August, Totternhoe Close is restricted for two days, and Morland Avenue is scheduled to reopen on 24 August.

The end of works on Morland Avenue in Kenton will be particularly significant for local traffic. The road has been closed since 28 April for water works, creating a scheduled restriction of almost four months. Its planned reopening on 24 August should restore a route that residents have been unable to use since the spring.

Sedgecombe Avenue creates the longest new Kenton closure during August. Works begin on 6 August and continue until 28 August, overlapping with the final days of the Willowcourt Avenue and Upton Gardens restrictions. Between 6 and 10 August, all three roads are scheduled to be closed at the same time.

When Kenton faces the greatest overlap

The most difficult period is likely to fall during the first full week of August:

1. Willowcourt Avenue remains closed until 10 August.
2. Upton Gardens remains closed until 10 August.
3. Sedgecombe Avenue closes on 6 August.
4. Morland Avenue remains closed until 24 August.
5. Totternhoe Close then closes on 14 and 15 August.

This does not mean every journey through Kenton will be blocked, but it increases the likelihood of traffic being displaced onto the same alternative routes. Short local trips may take longer where motorists must leave one residential grid and re-enter it from another direction.

The TfL register allows searches by street, postcode, borough and works owner. It can provide a more current picture when scheduled dates change or when lane restrictions are added near a full closure.

Wealdstone road closures combine gas and water projects

Three roads in Wealdstone enter August under active restrictions. Rusland Park Road has been closed since 2 June for gas works and is scheduled to reopen on 10 August. Marlborough Hill remains closed for gas works until 25 August, while Princes Drive is affected by water works until 24 August.

The timing creates a substantial overlap. All three restrictions are scheduled to be active from the beginning of August until 10 August, after which two remain in force for another fortnight. Residents travelling between Wealdstone, Harrow town centre and surrounding neighbourhoods may encounter changing diversion patterns as each road reopens. The expected sequence is:

• Rusland Park Road reopens after 10 August.
• Princes Drive reopens after 24 August.
• Marlborough Hill reopens after 25 August.

The original road list referred to “Rusland Park Avenue” in its introductory text but identified “Rusland Park Road” in the detailed schedule. The road name used in the closure list is Rusland Park Road. Anyone affected should confirm the precise site on the live map or local signage before travelling.

The difference of one day between the Princes Drive and Marlborough Hill reopening dates could determine when normal traffic patterns begin to return.

Gas and water works frequently require separate contractors and traffic-management plans. Even where two sites are geographically close, their reopening dates are not necessarily coordinated. A road may also remain restricted while the surface is reinstated after underground work has finished.

Short closures in Harrow Weald, Rayners Lane and South Harrow

Not every closure will last several weeks. Harrow Weald, Rayners Lane and South Harrow include a number of shorter restrictions with defined working windows.

Whitefriars Drive is scheduled to reopen after 5 August following three days of water works. Carmelite Road will close only on 25 August, from 9.30am until 3.30pm. The six-hour daytime window reduces the duration of disruption but may still affect school-holiday traffic, deliveries and access to nearby homes.

Fontwell Close is the main longer-term restriction in Harrow Weald. Gas works that began on 27 July are scheduled to continue until 28 August, keeping the road closed through most of the month.

Rayners Lane has two planned closures:

The consecutive dates mean the two restrictions could form part of the same broader period of water infrastructure work, although the published information does not state that they are directly connected. Village Way is scheduled to reopen at midnight as Highfield Avenue enters its closure period.

In South Harrow, St Johns Road will close from 19 to 21 August for telecommunications work. Gayton Road and Northwick Avenue were listed as closed until 3 August for water works, placing their scheduled reopening immediately before the date of this update.

Drivers should distinguish between a full road closure and nearby lane controls. A street may reopen while temporary signals, parking suspensions or pavement restrictions remain in place. The official Harrow Traffic Management Orders service explains how temporary restrictions are formally arranged.

Edgware and Pinner face closures lasting most of August

Edgware has two roads on the list. Bacon Lane remains closed for gas works until 10 August, having entered the restriction on 27 June. Oakleigh Avenue closed on 3 August for water works and is scheduled to remain unavailable until 28 August.

For residents near Oakleigh Avenue, the closure covers almost the entire month. Its timing overlaps with the final week of work on Bacon Lane, creating a period when two Edgware roads are simultaneously restricted. Pinner has one listed closure, but it is another month-long project. Cecil Park closed on 27 July for road maintenance and is scheduled to reopen after 31 August. Unlike most roads in the programme, where the stated purpose is utility work, Cecil Park is listed specifically for road maintenance.

The different work categories matter because they can produce different site conditions:

• Water works usually involve access to pipes, valves or service connections.
• Gas works can require excavation, pipe replacement and safety testing.
• Road maintenance may involve carriageway repairs, resurfacing or associated works.
• Telecoms works generally relate to underground ducts, chambers or network equipment.

The list does not provide technical specifications for each project. Details displayed at the site, formal notices and updates from the organisation responsible for the work should take precedence where they add more precise information.

How to plan journeys around Harrow roadworks

The most reliable approach is to check the route on the day of travel. Planned dates describe the expected working period, but traffic controls can be amended as work progresses. A project may finish early, require additional time or move between sections of the same street. Residents can reduce avoidable delays by following four practical steps:

1. Search the street or postcode on LondonWorks before starting a journey.
2. Check whether the restriction is a full closure, a lane closure or temporary signals.
3. Allow additional time where several nearby streets are affected.
4. Follow signed diversions rather than using narrow residential roads as unofficial shortcuts.

Access arrangements can vary. A “road closed” notice may prohibit through traffic while preserving controlled access for residents, refuse collections, emergency services or businesses. That distinction is decided through the traffic-management arrangement at each site and cannot be assumed from the headline dates alone. Peak pressure is most likely where several closures overlap. The first ten days of August bring simultaneous restrictions in Kenton and Wealdstone. The final week brings ongoing work in Hatch End, Kenton, Edgware, Pinner and Harrow Weald, plus new closures in Rayners Lane and Marsworth Avenue.

The longest individual disruption is in Hatch End, but Kenton has the greatest number of affected streets.

Morland Avenue is scheduled to reopen on 24 August, ending the longest-running active closure in Kenton, while Rusland Park Road should reopen earlier on 10 August. Blythwood Road will remain the major exception: its water works are due to continue until 30 October, well beyond the rest of the August programme. Road users should confirm conditions through Harrow Council, LondonWorks or the signage at each site before travelling. The schedule contains planned dates rather than a guarantee that every road will reopen at the start of the following day.
