Major works on a crucial UK road are to cause closures from September 24. Improvements to the A41 Brent Cross Flyover will allow heavy goods vehicles back on to the carriageway, with a 7.5 tonne weight restriction being lifted. Officials say the project will allow the flyover to stay open for decades to come, "helping prevent unplanned and very disruptive emergency closures". Drivers have been advised to plan ahead as journeys through the area are "expected to take longer while works take place".

The flyover is one of London's most important road structures. More than 120,000 vehicles use the wider Brent Cross Interchange every day. Transport for London (TfL) calls it "a vital strategic route for people, businesses and freight, connecting communities across north London and beyond". The Department for Transport (DfT) has supplied £10.8million for the scheme. Between late November and early January, works will be paused to allow for the festive season.

Officials say series of traffic measures from the evening of September 24, reducing the A41 Brent Cross Flyover to one lane in each direction. "Drivers should expect reduced road space and longer journey times," TfL said.

"There will also be a number of overnight and weekend lane and road closures during different stages of the project, to allow construction activities to take place safely and efficiently. 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 a range of measures to minimise disruption, including traffic signal improvements, travel demand management activity and targeted travel advice."

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."
