Transporter Bridges

Towards the end of the 19th century and into the early years of the 20th century, the problem of spanning wide rivers and canals, while maintaining headroom for navigation, was becoming a problem. The solution adopted to solve this problem was the transporter bridge that, in effect, was an aerial ferry that carried a segment of roadway (or platform) across the span. This problem was especially acute in flat country or urban areas where approach roads were at a low level making fixed bridges impractical. A typical transporter bridge consisted of a tower on either side of the span, which supported a girder at a sufficient height to be clear of navigation. Vehicles were then carried across the span on a large segment of roadway suspended by cables from a trolley running on rails along the girder.

This idea was first put forward in Britain in the 1870s but the first bridge to be built was by the French engineer, Ferdinand Arnodin, at Portugalete near Bilbao, Spain. This was completed in 1893 with a span of 164m and it is still in use.

Some 20 transporter bridges have been identified throughout the world of which five were built in Britain. These are:

  1. Widnes-Runcorn Transporter Bridge, built in 1905 and demolished in 1961. Span 304.8m.
  2. Newport Transporter Bridge, built in 1906 and still in use. Span: 196.6m.
  3. Middlesborough Transporter Bridge, built in 1911 and still in use. Span: 173.7m.
  4. Warrington Transporter Bridge, built in 1916 and last used in c.1964 but still extant. Span: 57m.
  5. Royal Victoria Dock Footbridge, London, built in 1998. Span: 128m. This footbridge over the dock differs in that the high-level bridge deck is accessed at each end by lifts (and stairs) located in towers.

The Widnes-Runcorn Transporter Bridge, 1950s.

This view shows the Runcorn end of the bridge from the Manchester Ship Canal and the river Mersey is off the picture on the right. The trolley and cables supporting the road platform are visible at the end of the girder.

The bridge had a span of 1,000 feet (304.8m) and it was in use until 1961 when it was demolished and replaced by a high-level, steel-arch bridge.

Warrington (or Bank Quay) Transporter Bridge, 23 February 1980.

This bridge across the river Mersey has a span of 187 feet (57m). It was built in 1916 and, although it has been out of use since c.1964, it is still extant.

It is privately owned and it was built to connect the two parts of the large chemical and soap works of Messrs Joseph Crosfield & Son Ltd.

It is listed by English Heritage as Grade II* but presently it is on their Buildings at Risk Register because of its poor condition. It is also a Scheduled Ancient Monument.
