Major works on the A41 Brent Cross Flyover will begin on September 24, causing closures and longer journey times for drivers. The £10.8 million project will strengthen the structure, allowing the current 7.5-tonne weight restriction to be lifted and enabling heavy goods vehicles back onto the carriageway.
Project aims and funding
Transport for London (TfL) says the improvements will allow the flyover to stay open for decades, "helping prevent unplanned and very disruptive emergency closures." The Department for Transport (DfT) has provided £10.8 million for the scheme.
The flyover is one of London's most important road structures, with more than 120,000 vehicles using the wider Brent Cross Interchange daily. TfL describes it as "a vital strategic route for people, businesses and freight, connecting communities across north London and beyond."
Works and traffic measures
From the evening of September 24, the A41 Brent Cross Flyover will be reduced to one lane in each direction. TfL says there will also be overnight and weekend lane and road closures during different stages of the project. Signed diversion routes will be in place, and residents and road users will be updated in advance.
Road users should expect longer journey times on the A41 and surrounding roads, including parts of the A406 North Circular Road, A5 Edgware Road, and A1. TfL will implement measures to minimise disruption, including traffic signal improvements, travel demand management activity, and targeted travel advice.
Works will be paused between late November and early January for the festive season.
Official comment
Stuart Harvey, TfL's Chief Capital Officer, said: "The A41 Brent Cross Flyover is a vital piece of London's road network, supporting tens of thousands of journeys every day. These works are essential to ensure it remains safe and reliable for the millions of journeys that depend on it. We recognise that the work will cause disruption, and we'd like to thank local communities and road users in advance for their patience. We will do everything possible to keep people moving and encourage those in the area to plan their journey in advance while this work takes place."
