The Dartford Crossing has been partly closed helping to add to earlier problems due to a serious accident on the A2.
The A2 Kent-bound has been closed most of the day around Bexley. The latest incident is causing mass congestion around Crayford, Dartford, Bexleyheath and also Greenwich as some drivers divert.
