Drivers were advised to plan alternative journeys after a major trunk road was closed because of flooding that had frozen over.

The A12 northbound carriageway in Essex between junction 12 near Mountnessing and junction 14 at Margaretting was shut on Tuesday morning.

National Highways said a drainage carrier pipe had become blocked in sub-zero temperatures.

A spokesman said at 18:51 GMT the stretch of road had reopened.

A 40mph speed limit was in place.

Crews earlier said they would build a bund wall around the pipe with sandbags, and then use a high-pressure jet hose to clear the blockage.

Motorists were asked to exit the A12 at the junction 12 (Marylands interchange), and use the B1002, before re-joining the A12 at junction 15 (Three Mile Hill near Chelmsford).
