A ferry boat named Ferret will operate at Benson from Sunday 7 May.
This service is being introduced whilst the foot crossing at Benson Lock is closed. Repair which has yet to commence is expected to take some time.
The ferry is to run upstream of the lock daily from 8am to 6pm; tickets £2 (child £1).
The landing on the Benson bank is at the Waterfront Cafe.
