The Clifton Suspension Bridge is a suspension bridge, which opened in 1864, spanning the Avon Gorge and the River Avon, linking Clifton in Bristol to Leigh Woods in North Somerset, England. Since opening it has been a toll bridge. The income from the tolls continues to provide funds for its maintenance. The bridge is built to a design by William Henry Barlow and John Hawkshaw, based on an earlier design by Isambard Kingdom Brunel.
