Longdendale Bypass

The Longdendale Bypass (also known as the A57/A628 Mottram-in-Longdendale, Hollingworth & Tintwistle Bypass) is a long-planned National Highways road scheme in the Tameside and High Peak districts in England, part of which is currently under construction. Its aim is to alleviate traffic congestion on the A57, A628, and A616 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. After nearly fifty years, part of the road scheme – the Mottram Bypass and Glossop Spur – was approved by the Highways Agency on 2 December 2014; but almost a decade later, shovels were still to be seen on the ground. Construction was intended to start in Spring 2023, but appeals to the High Court meant construction did not start. The High Court dismissed the appeals against the bypass in November 2023. A final legal challenge to the bypass failed in April 2024, leaving National Highways free to begin constructing the road. Construction began in 2025.
