Brent Cross flyover used by more than 120,000 vehicles a day is set to undergo major ‘safety-critical’ repairs. The north London flyover on the A41 has been under a weight restriction since October 2022 as a safety measure. All vehicles weighing more than 7.5 tonnes have had to use diversions since then, pushing heavy vehicles onto nearby local roads. The works, set to start tomorrow and last for up to two years, mean journeys will take longer and lanes are reduced, TfL warned.

The main roads that will see changes during the works are A41, A406 North Circular and other surrounding roads. Drivers should brace for disruption from the following lane restrictions and overnight closures: Lane restriction on A41 Hendon Way between Thursday, October 1 and Wednesday, October 28, 2026 Contraflow system on A41 flyover from October 29 Overnight closure on A406 North Circular westbound only Wednesday, September 30 from 10pm until 5am the following day Overnight closure A41 Hendon Way southbound from Vivian Avenue and The Vale junctions on Thursday, October 1 and Friday, October 2 10pm-5am Overnight closures A41 Hendon Way northbound between Vivian Avenue and The Vale junctions on Monday, October 5 and Tuesday, October 6 between 10pm-5am TfL urged motorists to avoid the A41 and A406 Brent Cross area where possible, allow more time for journeys and walk, cycle or take public transport where possible. Buses will continue to operate in the Brent Cross area, but especially during night closures, services might have to follow diversions and use different stops than usual. Works will pause between November and early January to minimise disruption on the Brent Cross Shopping Centre and shoppers during the festive period. Latest London news What transport upgrades are happening in London? London and its gigantic transportation network, which includes the Tube, London Overground, and National Rail lines, is always changing. These are all of the transport upgrades happening in the capital right now: South Kensington Tube station is undergoing an extensive £120,000,000 upgrade to tackle overcrowding and improve accessibility.

Why are works carried out on Brent Cross flyover? Checks carried out on the flyover found that the maximum weight it could carry was lower than what previous inspections deemed, so a 7.5 tonne weight limit was imposed. Works include strengthening the flyover’s structure, replacement of safety barriers on the flyover and on approach to boost driver safety and a new waterproofing system. TfL said: ‘The A41 Brent Cross flyover is one of London’s most important road structures. Over 120,000 vehicles use the wider Brent Cross Interchange every day. ‘It is a vital strategic route for people, businesses and freight, connecting communities across north London and beyond. ‘This work will reduce the risk of future unplanned closures and emergency repairs.’ It received £10.8 million in funding from the government for the project.
