The A14 has reopened following a serious crash that left parts of the major road closed for several hours overnight.

The incident happened at 12.20am on Saturday on the eastbound carriageway of the A14 - between junction 35 for Cambridge and junction 37 for Newmarket - when three cars crashed into each other. 

Police, fire and ambulance services were all called to the scene.

As of 10.31am this morning, both the eastbound and westbound carriageways have now reopened.

The closure was previously in place on the westbound carriageway - between Newmarket and the A11 Six Mile Bottom - due to "a large amount of debris" blocking all lanes.

According to National Highways, one car "rolled" following the collision and specialist clear-up crews were on standby.

A spokesperson for National Highways said: "There is no indication at this time how long this closure will be in place for.

"Cambridgeshire Constabulary are beginning to turn traffic caught within the closure around on the A14 and send them back to J35. This will take some time.

"There is no official diversion route for eastbound traffic which is instead being diverted via local routes. Westbound traffic is advised to exit the A14 at J37, travelling via the A142, A1123 and A10 to re-join the A14 at J33."
