The Highways Agency says the northbound A34 is likely ot be closed between the A4130, Milton and the A415, Abingdon, throughout the day and into this evening’s rush hour.
The road is closed following an accident, which happened at around 4.40am this morning, involving two HGVs. The Highways Agency and Thames Valley Police are working to reopen the carriageway.
The operation to remove the lorries has been complicated because the load on one of them has shifted. There is also a diesel on the carriageway which will need to be cleared up. There are long delays on other roads in the area.
