The Milton Keynes redway system (locally known as Redways) is a 273 km (170 mi) network of shared use paths for cyclists and pedestrians in Milton Keynes, Buckinghamshire, England. It is generally surfaced with red tarmac, and criss-crosses most of the city. Some of these Redways run next to the grid roads and local roads, with underpasses or bridges where they intersect major roads. Others run through park land and along the floodplain of the Great Ouse and its tributaries.
