The northbound Blackwall Tunnel remains closed this afternoon, following a corrosive liquid spill affecting over 1km of the inside of the tunnel.
Since 7am, fuel and hydraulic fluid have leaked from a mobile crane, causing the the tunnel to become unsafe. According to TfL, work is currently under way to resurface the road — meaning the northbound tunnel will remain closed for the remainder of the day.
On Twitter, TfL has advised motorists to seek other routes:
Hi @jamesnewe The Blackwall Tunnel is unlikely to reopen any time soon. Best to seek an alternative route— TfL Traffic News (@TfLTrafficNews) May 24, 2016
Garrett Emmerson, TfL's Chief Operating Officer, said, "We apologise to drivers and bus passengers who have been affected by today's closure... Contractors on-site have cleared the road and now need to repair the road surface."
All other non-essential roadworks in the area have been suspended to reduce the impact on surrounding roads, but this morning saw tailbacks of 10 miles for some commuters.
Bus passengers have also been affected, with eight routes using the tunnel diverted. The southbound tunnel remains open, but is heavily congested.
