About Holt Fleet Bridge

The first bridges were probably of felled trees lain across the river (Stockbridge and Trowbridge both refer to tree trunk bridges) and then of worked timber.

The Romans built bridges in wood, and probably stone, but none remain in Britain. The oldest surviving timber bridge is over the River Ouse at Selby and dates from 1790.

The first simple stone bridges - clapper bridges comprise large slabs of stone rested on stone piers to span a stream or small river. Tarr Steps, which crosses the River Barle in Somerset, is the longest with 17 spans supporting stone slabs 5 feet wide. It is too narrow for carts but Pont Sarnddu in Carnarvonshire is ten feet across and wide enough for vehicles.

Packhorse bridges, small arched bridges, with very low parapets so as not to get in the way of the horse's panniers, can still be found for example at Wycoller in Lancashire, Moulton in Suffolk, and Fifehead Neville, Dorset.

More sophisticated stone bridges were built abundantly in the 13th century, the use of timber continued into the 16th century. The river Skell at Fountains Abbey, Yorkshire, is crossed by probably the oldest arched bridge in England. Thirteenth to fourteenth century bridges can be recognised by their pointed arches and by the V-shaped extensions over the cutwaters for pedestrian refuges. These were superseded by bridges which were ribbed under the arches (14/15century), and those with semi-circular arches.

But all of these styles are modified by the needs and knowledge of the locality. In the early eighteenth century Daniel Defoe observed "...the Nyd, smaller then the Wharfe, but furiously rapid, and very dangerous to pass in many places, especially upon sudden rains. Notwithstanding, such lofty high built bridges are as not to be seen over such small rivers in any other place".

Masonry arch and cast iron bridges derive from the late 18th and 19th centuries. Bridges were usually made from local materials. In the eastern counties they were first built with timber and then brick.

Holt Fleet Bridge, also known as Holt Bridge, is a cast iron arch bridge over the River Severn, at Holt in Worcestershire. It has a span of 150 feet (46 m), was designed by Thomas Telford, and opened in 1828. It is similar to Telford's Galton Bridge, which spans his canal at Smethwick.

The bridge was built with five cast iron ribs, with X-braced spandrels, as were several of Telford's bridges. It was strengthened in 1928, when the upper and lower parts of each rib and some of the diagonal struts above them were encased in concrete. The road deck was rebuilt in reinforced concrete and widened at the same time.

Semicircular arches at each end, built in red sandstone, allow for the passage of riverbank foot-traffic and floodwater.
