Two broken down vehicles are massively slowing down commuters trying to get through the Blackwall Tunnel this morning (January 15).

At around 8.20am, TFL announced that lane two of three is blocked on the northbound road in Greenwich entering the tunnel.

Barely ten minutes later, it announced another broken down vehicle was blocking lane one of three.

With only one lane free, traffic is slow and heavy travelling north through the tunnel.

Met Police are on the scene and delays of at least 20 minutes are expected.
