Gloucester is linked to the Severn Estuary by the Gloucester and Sharpness Canal, which is navigable by small coasters. The city is linked to the River Avon and Stourport-on-Severn by the navigable part of the River Severn, which is navigable by river craft of a few hundred tonnes' displacement. Gloucester Docks mark the Normal Tidal Limit (NTL) of the river. Gloucester was formerly linked to Ledbury and Hereford by the Herefordshire and Gloucestershire Canal; and subsequently by the Ledbury and Gloucester Railway, which used the southern section of the former canal, until it also closed in 1964. This canal is now being restored, and the restored canal basin in the adjacent village of Over is a local attraction.
