Double-decker bus crashes in west London causing serious congestion - live
A double‑decker bus crashed onto the A40 near Northolt, creating extensive traffic jams on Western Avenue and disrupting several London Underground lines. The incident began before 5 am and led to lane closures and severe delays on the Piccadilly, Metropolitan, and Bakerloo lines.
A double‑decker bus left the A40 near Northolt in west London early on Tuesday, creating a major traffic bottleneck on Western Avenue and causing significant delays on several London Underground lines.
What Happened
At about 4:45 am, a TfL-operated double‑decker bus veered off the A40 and came to rest in the roadside shrubbery. Video footage posted on social media shows the vehicle partially on the carriageway before it was forced onto the verge. The crash immediately closed one lane of the three‑lane westernbound carriageway, triggering a queue that stretched from Swakeleys Roundabout to Northolt Park.
Immediate Impact on Road Traffic
Traffic monitoring services reported that the lane closure on Western Avenue caused long delays and forced motorists to detour onto the A312 Church Road. By 12:20 pm, Inrix data indicated that traffic was moving at a fraction of normal speed, with some vehicles unable to pass the obstruction for several miles.
Drivers heading into central London were forced to navigate a series of detours, including the Westfield Avenue junction and the West End Road. The congestion spread to nearby roundabouts, such as Hillingdon Circus and the Swakeleys Roundabout, creating a ripple effect that disrupted local traffic patterns for hours.
Rail Disruptions Across Multiple Lines
The crash coincided with a signal failure at Harrow‑on‑the‑Hill, which compounded delays on the Metropolitan line between Harrow‑on‑the‑Hill and Uxbridge. Service on the line was severely disrupted, with trains running at reduced frequency and some stations experiencing complete closures.
Other Underground lines also felt the impact. The Piccadilly line suffered significant delays between Wood Green and Cockfosters due to a signal failure at Turnpike Lane. The Bakerloo line experienced severe delays after a signal failure at Stonebridge Park, while the Central line had minor delays between Loughton and Epping as engineers repaired a track fault at Epping.
The DLR also reported minor delays between Bank and Canning Town while engineers worked to fix a faulty train at Poplar. Passengers on the Lioness line were advised to seek alternative routes as the line remained suspended into rush hour because of the same signal failure at Stonebridge Park.
Current Status and What to Expect Next
By midday, the lane on Western Avenue was still partially blocked, with recovery teams working to clear the bus and restore full traffic flow. The bus remains on the verge, and authorities have not yet announced when the road will be fully reopened.
Rail services have begun to return to near‑normal levels, though occasional delays persist as engineers complete the necessary repairs. Commuters are advised to monitor real‑time updates from Transport for London and to consider alternative routes or modes of transport if traveling through the affected corridor.
Why It Matters
Incidents like this highlight the vulnerability of major transport arteries in London and the cascading effects a single crash can have on both road and rail networks. Understanding these disruptions helps commuters plan better and underscores the importance of robust infrastructure maintenance and emergency response protocols.
