Plans to re-route the Wilts & Berks canal through the centre of Melksham are to be shown at an exhibition.
The plans are on show at Melksham library
Much of the original canal was lost to housing, and redirecting it around the town would offer no benefits, said Wilts & Berks Canal Trust.
It has proposed a route following the River Avon through the town, connecting the Kennet & Avon Canal to the Thames & Severn Canal.
The plans go on shown at Melksham library from 9 to 14 July.
The proposals include a new weir south of the bypass bridge, behind which the river level will be raised to allow sufficient depth for navigation.
The existing weir upstream of the town bridge would be removed.
Unsightly walls and banks would be partially covered and under-planted with wetland species.
Moorings would be provided, and linked to the town through the provision of new paths and cycleways, the trust said.
Colin Fletcher, from the trust, said: "The charity and our partners have strived for many years to find a route that will satisfy most parties, and we believe this new plan represents our most realistic chance of success."
