The emergency services, working with army bomb disposal officers, are currently at the scene of a building site on Milestone Way in Chasetown, Burntwood, following the discovery of a large number of mortar shells.
As a precautionary measure, a 100m cordon is in place and several local businesses have been evacuated to ensure public safety.
Any live shells will be detonated safely under controlled conditions. The A5190 will close when any devices are detonated on site, while other devices will be taken to a second side for safe detonations.
People are reminded to avoid the area if at all possible and are thanked for their patience and cooperation.
