Developing story: A serious crash has blocked the A503 in north London this afternoon. This is a developing story and will be updated as more details are confirmed.
A serious crash has closed a section of the A503 Tollington Road in north London on Friday afternoon, blocking the one-way route and triggering long queues of traffic.
The collision was reported during the afternoon, with the AA warning drivers of a blocked road and queueing traffic on the route. Congestion is building towards Finsbury Park as vehicles stack up behind the closure.
Tollington Road runs through Islington, forming part of the busy A503 corridor that links the Finsbury Park area with Camden. The road is a key artery for motorists and bus services alike, and closures here regularly send ripples across the surrounding streets.
Detours have been put in place around the affected stretch while the incident is dealt with. Drivers are being urged to avoid the area, follow signed diversion routes and allow plenty of extra time for journeys.
Bus services through the area are also caught up in the disruption, with routes along Tollington Road facing diversions and delays. Passengers are advised to check live departure information before travelling.
Motorists stuck in the queues are advised not to rely on sat-nav shortcuts through residential streets. Anyone travelling through the area this evening should consider alternative routes or public transport where possible.
The closure adds to a difficult period on the capital’s transport network. Drivers are already being warned of road closures and bus diversions across London this weekend for a packed events calendar, while major engineering works will hit London Overground services on 26 and 27 September.
Bus provision in the capital has also been under the spotlight this week, after a council urged TfL to rethink planned bus cuts in Hackney as a consultation drew to a close.
Details of the crash are still emerging and it is not yet known how long the road will remain shut. This is a developing story — further updates will follow.
