A KEY route in Darlington will be closed for five nights from Monday.

The B6820, which is the top end of Yarm Road, will be closed from the A66 Morton Palms roundabout between 8pm and 6am.

Traffic will be diverted via McMullen Road.

There will also be a series of overnight lane closures and occasional additional full carriageway closures.

When needed, local diversion routes will be clearly signed. The works will be on until the end of April, Highways England said.
