TRAFFIC is building after overnight roadworks at the QE2 Bridge overran.

Two lanes at the Dartford Crossing are closed whilst tarmac is setting from the emergency works overnight.

All lanes were shut at 7am today though two have now reopened.

Highways England has advised all lanes should be open soon but there is three miles of congestion on approach on the southbound carriageway.

Delays are estimated to be at 20 minutes.

The lanes are shut from junction 31 for Lakeside and junction 21a for Swanscombe.
