A trailer overturned on a busy dual carriageway near a major roundabout yesterday.

Police were called to reports of a crash on the A414 by the Park Street roundabout just before 2.20pm on Monday March 8.

Photos taken by an officer at the scene show a trailer on its site blocking the carriageway but the vehicle cab stayed upright.

Until the trailer was recovered, there was no access onto the A414 towards London Colney.

A police spokesperson said: "Officers attended and closures were put in place while the lorry was recovered and debris was cleared.

"The road was reopened by 3.55pm. No one was injured."
