High Quality Content by WIKIPEDIA articles! The Longdendale Bypass (also known as the A57/A628 Mottram-in-Longdendale, Hollingworth & Tintwistle Bypass) was a controversial road scheme in England (abandoned in March 2009) by the Highways Agency. The aim was to alleviate traffic congestion on the A57 road/A628 road/A616 road routes that presently pass through the villages. There is both strong support and opposition for this long-planned scheme which would have passed through the valley of Longdendale and part of the Peak District National Park.
