Blackwall Tunnel crash causes major disruption for London commuters
A Blackwall Tunnel crash has brought traffic to a near standstill in southeast London this morning, with two people taken to hospital and widespread disruption for drivers heading into the city. The northbound A102 approach has been fully closed since the early hours, with long tailbacks and gridlock stretching through Kidbrooke and back to Eltham Tunnel.
The collision, which occurred around 1:30am on Wednesday 4th June, shut the stretch of road between the Sun in the Sands roundabout (A2) in Blackheath and the Woolwich Road Flyover (A206) in Greenwich. Police and emergency services responded quickly, and two people were taken to hospital for treatment. Their condition is not currently known.
Transport monitoring services have warned drivers to expect long delays through the morning rush hour. The Blackwall Tunnel crash has had a knock-on effect across southeast London, with congestion building both north and south of the river. According to National Highways, queues are forming as far back as Kidbrooke, and buses have been diverted from their usual routes.
Southbound traffic heading out of the tunnel has also been impacted, with drivers reporting delays along Blackwall Lane and other key feeder roads.
Photos posted on X earlier this morning showed vehicles at a standstill well before sunrise, with tail lights stretching across the carriageway and minimal movement across key junctions. Many commuters have taken to social media to share frustration at the lack of early warnings or live diversion updates.
The Blackwall Tunnel crash is the latest in a string of incidents affecting key London routes in recent weeks, raising ongoing questions about the vulnerability of the city’s transport infrastructure. With few alternative routes for those travelling from southeast London into the centre, even minor incidents in the tunnel can trigger significant delays.
Motorists have been urged to avoid the area if possible and to consider alternative crossings such as the Woolwich Ferry or Dartford Crossing, although both are also expected to see heavier volumes due to diversion. TFL’s live travel map continues to update with reroutes, while some services are posting direct updates via their social feeds.
For now, the northbound side of the A102 remains closed, and no official time has been given for reopening. Drivers are advised to check before travelling and leave additional time.
