The Longdendale Bypass (also known as the A57/A628 Mottram-in-Longdendale, Hollingworth & Tintwistle Bypass) is a long-planned road scheme in England by the Highways Agency. The aim is to alleviate traffic congestion on the A57 road/A628 road/A616 road routes that presently pass through the villages. There is both support and opposition for this long-planned scheme which will pass through the valley of Longdendale and part of the Peak District National Park.
