Chard Canal
United Kingdom
The Chard Canal was a 13.5 miles (21.7 km) tub boat canal in Somerset, England, that ran from the Bridgwater and Taunton Canal at Creech St. Michael, over four aqueducts, through three tunnels and four inclined planes to Chard. It was completed in 1842, was never commercially viable, and closed in 1868. The major engineering features are still clearly visible in the landscape.
