A CYCLIST and van were involved in a crash on Magdalen Bridge in Oxford.

The busy bridge was completely closed to westbound traffic shortly before 9am this morning, but all lanes have since reopened. 

Traffic at The Plain was being diverted south on Iffley Road, Oxfordshire County Council said, and buses were also affected.

The Oxford Tube tweeted shortly before 10.30am reporting that its buses are now serving all stops as normal.

Two fire engines and a police car were at the scene, and one passer-by said he saw a van cordoned off with police tape. 

Another witness said it appeared as though people were treating someone on the ground, but he could not see an ambulance or paramedics.

There was heavy traffic from the A420 St Clement's Street to Longwall Street.
