TWO separate crashes are causing delays on the A12.

A lane was blocked on the London-bound carriageway between Ardleigh Interchange and the JobServe Community Stadium.

The scene has now been cleared but there are still long delays.

Traffic is also very slow at Marks Tey.

A separate accident has been reported between Dedham and East Bergholt on the Ipswich-bound carriageway further along the A12.

Queues for this are also reported to be back as far as the Ardleigh Interchange.
