Motorists and residents in the London Borough of Harrow are set for a mixed month of transport news, with several significant road closures planned for December alongside the welcome reopening of key routes that have been shut for months.
Long-Awaited Reopenings Bring Relief
A major piece of good news for drivers is the scheduled reopening of Clamp Hill in Harrow Weald. This important route has been closed since October 7 for extensive gas works. Its reopening was initially planned for November 24 but faced delays. It is now finally expected to reopen to traffic on December 8.
Other roads are also set to return to normal at the start of the month. Roads in Harrow Weald and Kenton that have been closed for water and gas works respectively will reopen, easing congestion in those areas.
New and Ongoing Disruptions for December
However, new closures will also come into effect, meaning drivers need to stay alert to diversion signs. According to data from the official one.network service, compiled by the Local Democracy Reporting Service (LDRS), several works will cause disruption.
Some closures will be in place only overnight, while others will last for weeks. Residents are advised to plan journeys ahead to avoid substantial delays.

The following is a breakdown of key ongoing and planned closures for December and beyond:
- Scot Grove (Hatch End): Road closed from November 21 to January 23, 2026 for Thames Water maintenance works.

Planning Ahead for the Festive Season
With the festive period approaching, these works could impact shopping trips and holiday travel. The closure of Scot Grove is particularly lengthy, extending well into the new year.
Local authorities and utility companies are urging drivers to pay close attention to signed diversion routes. Staying informed about these Harrow road closures is the best way to minimise disruption during a busy month on the roads.
