Department of Infrastructure assessing cause
Motorists using the Mountain Road this morning are being warned of a large bump in the road surface which has appeared overnight.
The affected area is on the Ramsey-bound side of the road at Hillberry, near the de-restricted section.
The Department of Infrastructure is aware, and is assessing the cause.
As a result, there could be works in the area later today, which may lead to disruption.
