Long queues have formed on the A12 this morning after a lorry overturned.

The incident happened on the northbound carriageway and all lanes have now been shut as a result. 

It happened sometime around 6am today (Monday, October 11). 

The closure means queues have formed several miles back past junction 25 at Marks Tey on the northbound carriageway. 

There are also some delays on the southbound side.
