 The 1936 breach was never repaired and presents a significant gap in the canal 's route . On the Salford arm , although in good condition , the top three locks at Prestolee are derelict ; the bottom three have been removed . The canal is in water from the bottom of the lock flight through to Ringley Locks . Ringley Bridge is infilled , as is the canal through Ringley Village and Giants Seat Locks . Kilcoby Bridge is missing and from there the canal is inaccessible until it reaches the M60 motorway . Overgrown , Rhodes Lock is still in reasonable condition . One or more electricity pylons straddle the infilled canal between Rhodes Lock and the motorway , which has been built over the line of the canal . A sludge lagoon built during the motorway 's construction blocks a short section toward Clifton Aqueduct . The canal does not take water again until beyond Clifton Aqueduct , where a short 900 @-@ foot ( 270 m ) length exists between the former Pilkington factory and the Enersys factory . Lumn 's Lane Aqueduct is missing but the canal is in water between there and Holland Street . Beyond this point the canal is infilled and in parts built over , especially through Pendleton . Its junction with the River Irwell in Salford has recently been restored and made navigable .
