Brentford High Street has been shut in both directions after a crash outside the Lidl supermarket, with a stretch of the busy A315 closed to traffic.
The road is closed between Half Acre and Alexandra Road — a central section of Brentford’s High Street — following the collision. Drivers are being told to avoid the area while the closure is in place.
The crash happened outside the Lidl store on the High Street, on one of west London’s main east-west routes. No further details about what happened or whether anyone was injured have been released.
Where is closed and why it matters
The A315 High Street is the spine of Brentford, running through the town centre and linking the area to Chiswick and Kew in one direction and Hounslow in the other. Closing it both ways between Half Acre and Alexandra Road cuts off a key through-route, and traffic is likely to build quickly on surrounding streets.
The closed stretch runs right through the heart of the town. Half Acre leads down towards Watermans Park and the Thames, while Alexandra Road sits at the eastern end of the centre — between them are shops, restaurants and the Lidl store outside which the crash happened. Brentford’s Gtech Community Stadium, home of the Bees, sits just north of the High Street off Lionel Road South, though the closure itself is on the High Street rather than near the stadium.
Drivers heading through Brentford will need to find an alternative route — the A4 Great West Road runs roughly parallel to the south of the High Street and is the most obvious alternative for through-traffic, while local trips may be easier to reroute via Boston Manor Road or Ealing Road depending on direction.
Public transport can take some of the strain: Brentford railway station is served by South Western Railway trains towards London Waterloo and Hounslow, and lies a short walk from the High Street for anyone who would normally drive through the closure.
Check before you travel
As with any unplanned closure, the best advice is to check TfL’s status pages and traffic feeds before setting off, and to allow extra time if your journey takes you through Brentford. Bus routes serving the High Street are likely to be delayed or diverted around the closure.

What happens at a crash scene
When a road is closed like this, it usually means emergency services are still on the scene. Police will secure the area and manage diversions, ambulance crews treat anyone hurt, and fire crews can be called in if vehicles need to be made safe or passengers freed.
Once the scene is dealt with, recovery vehicles remove any damaged cars and the road surface is checked for debris, oil or damage before traffic is allowed back through. It is a step-by-step process, which is why even a relatively straightforward crash can keep a main road shut for hours.
Anyone who saw what happened is usually asked to come forward with dashcam or doorbell footage, which can help establish how a collision unfolded.
A week of London road closures
The Brentford shutdown is the latest in a string of crashes closing London roads this week. High Road in Tottenham was shut in both directions yesterday after a man was rushed to a major trauma centre, while Judge Heath Lane in Hayes was also closed following a collision.
Police and traffic teams will typically keep a road shut until vehicles are recovered and any debris cleared — so closures of this kind can last several hours even after the initial incident. Where a crash is more serious, the road may stay closed longer while collision investigators document the scene.
