High Quality Content by WIKIPEDIA articles! The Manchester Bolton Bury Canal is a disused canal in Greater Manchester, England, built to link Bolton and Bury with Manchester. The canal, when fully opened, was 15 miles 1 furlong (24.3 km) long. It was accessed via a junction with the River Irwell in Salford. Seventeen locks were required to climb to the summit as it passed through Pendleton, heading northwest to Prestolee before it split northwest to Bolton and northeast to Bury. Between Bolton and Bury the canal was on the same level and required no locks. Six aqueducts were built to allow the canal to cross the rivers Irwell and Tonge, as well as various minor roads.
