A side of the northbound A12 carriageway was closed at the Copdock interchange after the road was partially blocked by a broken down lorry.

Suffolk police were called at 2.20pm today after reports of a “stalled” truck on the A12 at junction 55 with the A14.

The closure is causing a gradual build-up of slow-moving and queuing traffic back to the junction with Roman Road.

Recovery vehicles have been called to the scene, with Suffolk Constabulary officers currently waiting at the scene.

Officers on social media say that one of the lanes remains open on the northbound side but warn motorists to expect delays on approach.

Highways England were originally set to re-open the road between 4pm and 4.15pm.

However it was not opened until 4.40pm.

Police were able to leave the scene shortly after.

No other emergency services were needed to attend the scene.
