Transport for London (TfL) is reminding London’s road users that the Staples Corner Flyover on the North Circular (A406) will be closed for three weekends in September for essential refurbishment.


During the closures all main and local roads in the surrounding area will be extremely busy, so road users are advised to allow more time for journeys and use alternative routes where possible.

The closures are to allow a 40-strong workforce to replace two 22-metre long steel expansion joints. The joints, which are vital to allow the flyover to cope with temperature change, were repaired 11 years ago, but are now in a poor condition and need replacing to avoid long-term disruption to motorists.

TfL considered every alternative to the full closure of the flyover, however to do this essential work using part-closures would have taken nearly 50 days and would have affected many more road users.

The flyover will be fully closed in both directions between the following times:

22:00 Friday 1 September - 05:00 Monday 4 September

22:00 Friday 8 September - 05:00 Monday 11 September

00:01 – 23:59 Sunday 17 September

In addition to the three full weekend closures, preparation and resurfacing work will also affect traffic at other times:

The flyover is being reduced to one lane in each direction for four consecutive nights between 22:00 and 05:00 from Monday 28 August to Thursday 31 August

The flyover will be closed eastbound from 22:00 Monday 18 September to 05:00 Tuesday 19 September, and westbound from 22:00 Tuesday 19 September to 05:00 Wednesday 20 September

Leon Daniels, Managing Director of Surface Transport at TfL, said: “We’re sorry for the disruption this vital refurbishment of the Staples Corner Flyover will cause. We will be working as fast as we can to replace the expansion joints, which is essential to extend the life span of the flyover. During the closures road users in the area should allow more time for their journeys and, where possible, consider alternative routes.”

TfL has a number of measures in place to help reduce the impact of the closure, including:

Rapid response units placed around the area on standby to clear any incidents or accidents on surrounding roads

Messaging advising drivers of the closures

Re-phasing of traffic signals in the area to reduce disruption as much as possible and ease displaced traffic

Cancellation of any non-urgent roadworks in the local area

TfL will be providing up-to-date information through the @TfLTrafficNews and @TfLBusAlerts Twitter feeds and on tfl.gov.uk/trafficnews to help drivers and bus users. More information about the project can be found here: tfl.gov.uk/northwest-london-major-roadworks.
