The Dartford Tunnel has been shut down due to significant damage caused by a lorry collision on Friday. Extensive repairs are needed, leading to major traffic delays in the area. The incident occurred when an oversized lorry struck the tunnel’s roof, causing damage to its ventilation, CCTV, and fire detection systems. The west tunnel, spanning from J1A at Littlebrook Interchange, Dartford, to J31 at Purfleet-on-Thames/West Thurrock, is currently closed for repairs.

Repair crews are working in shifts to fix the damage, but due to the extent of the repairs required, the tunnel is expected to remain closed throughout the day. While the right tunnel is open for traffic, drivers should anticipate delays. National Highways has advised motorists to expect congestion near the Dartford Tunnels and to plan for extra travel time or consider alternative routes.

National Highways expressed understanding for the inconvenience caused by the closure and assured that efforts are ongoing to swiftly reopen the damaged tunnel once it is safe to do so.
