This article is about the Class III road numbered C522 maintained by Sunderland Council. For other roads numbered C522, see C522.
The C522 is a short route in the vicinity of Hetton-le-Hole, to the south-west of Sunderland. It begins at a T-junction on the B1284 North Road in the north-west of the town and heads west into open country along Hazard Lane. It passes the entrance to Hetton School then runs between fields as a wide country road. Hazard Lane becomes Robin Lane and the road skirts the southern edge of East Rainton before returning to open country and reaching the local authority boundary shortly afterwards.
