There is a 17-ton MGW (maximum gross weight) restriction over the bridge spanning the Widdale Beck in Appersett. Because of this, heavy eastbound traffic must leave just before the bridge and proceed onto an unclassified road through Hardraw and then turn south onto Burnt Acres Lane bringing the vehicles back to the A684 just east of Hawes town centre. Heavy westbound traffic from the B6255 is expected to go through Hawes eastwards and then back through Hardraw to avoid the weight restriction.
