The A90 near Brechin is undergoing three weeks of inspection works – months after the road was closed for repairs.

Work on the northbound carriageway commenced on Sunday and is set to run until Monday July 14.

Amey, on behalf of Transport Scotland, is undertaking investigation work to assess the condition of the road’s surface and safety barriers.

The section of the road faced scrutiny from motorists in January when large potholes caused several cars to break down on the road.

It is not known if the investigation is connected to potholes, or if it will lead to more roadworks on the road.

The contraflow that is currently in place will remain until Tuesday.

During this time:

The A935 St. Ann’s junction (Castle Centre exit) northbound on-slip to the A90 will be closed.
- Traffic will be diverted through Brechin to the B966 Keithock junction on slip for the A90, where they can access the A90 northbound.
The A90 northbound off slip to the B966 Keithock junction (Trinity exit) will also be closed.
- Traffic can exit the A90 northbound at the A935 St. Ann’s Junction and follow the route through Brechin to Keithock.

- Traffic can access the A90 southbound via the A935 St. Ann’s junction.
