 Six aqueducts were required to allow the canal to cross the River Irwell, the River Tonge and four roads. On the Bolton arm these were Hall Lane Aqueduct, Fogg's Aqueduct and the larger Damside Aqueduct, all of which have since been demolished. Hall Lane Aqueduct was damaged by mining subsidence and replaced in 1884 – 1885. It was demolished in 1950. The Salford arm flowed over Prestolee Aqueduct, then Clifton Aqueduct, and finally the smaller Lumn's Lane Aqueduct (since demolished).
