Clifton Suspension Bridge

The Clifton Suspension Bridge is a suspension bridge spanning the Avon Gorge and the River Avon, linking Clifton in Bristol to Leigh Woods in North Somerset. Since opening in 1864, it has been a toll bridge, the income from which provides 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.

It is a Grade I listed building and forms part of the B3129 road. The idea of building a bridge across the Avon Gorge originated in 1753. Original plans were for a stone bridge and later iterations were for a wrought iron structure. In 1831, an attempt to build Brunel's design was halted by the 1831 Bristol riots, and the revised version of his designs was built after his death and completed in 1864.

Although similar in size and design, the bridge towers are not identical, the Clifton tower having side cut-outs, the Leigh tower more pointed arches atop a 110-foot (34 m) red sandstone-clad abutment. Roller-mounted "saddles" at the top of each tower allow movement of the three independent wrought iron eyebar chains on each side when loads pass over the bridge.

The bridge deck is suspended by 162 vertical wrought-iron rods in 81 matching pairs. The Clifton Bridge Company initially managed the bridge under licence from a charitable trust.
