In page River Tone:

"

The river passes over weirs at Greenham, Tone and Nynehead, after which it is crossed by the Bristol and Exeter Railway. A disused bridge, constructed in 1817,[8] spans the river at Nynehead.[9] The river turns to the north-east near Bradford on Tone, with its two listed bridges, including the Bradford Bridge which was originally built by the 15th century,[10][11] and then to the east near Upcott bridge, where there were two mills. At Roughmoor its course is crossed by Silk Mills Road. There is a scheme to make the river navigable from here to the town centre as a way of encouraging transport with less environmental impact.[12]
