The permanent closure of the main A625 road at Mam Tor in 1979 due to subsidence has resulted in Winnats Pass being heavily used by road traffic. However, the narrowness of the road and its maximum gradient of over 28% (1 in ​3 1⁄2) has caused it to be closed to buses, coaches and vehicles over 7.5 tonnes in weight. The road regularly features in the Tour of the Peak cycle race each autumn.
