Also, the bridge was subjected to frequent heavy loading by freight trains in WW2. Brunel had to take the two tracks of the South Wales Railway across the River Wye.
In the 1950s, the speed of trains using the bridge was restricted to 15 miles per hour (24 km/h), because some of the girders had become distorted.
on the River Wye between Beachley Point (Junction of the River Severn and the River Wye ) (3 miles to the south) and Bigsweir Bridge (Normal Tidal Limit) (12 miles to the north). The bridge filled a gap in the main rail line between Brunel recognised that a circular cross-section tubular girder – a shallow "bow", excellent in compression and tension – could be strung by suspension chains to form a stiff, self-supporting structure very much lighter (thus less expensive) than a Stephenson-type box girder.

In spite of his extreme distrust of the use of cast-iron girders for such purposes, Brunel refused to condemn them when cross-examined as an expert witness.
However, Brunel's solution for the latter was to make a leap forward, based, nevertheless, on sound engineering principles and a variation of the tied-arch theme. Grace's Guide web site design is Copyright © 2020 by Grace's Guide Ltd. With regard to the appearance of the bridge, the Illustrated London News stated that "the peculiarity of the site did not permit any display of 'Art' - that is, of architectural embellishment; indeed, a pure taste rejects any attempt to decorate a large mechanical work with sham columns, pilasters, and small ornamental details." Brunel’s original pillars still support the bridge but Brunel’s rail deck structure was replaced in 1962; 3. The bridge deck was rigid, because it was effectively clamped against the tubes by the chains. Brunel solved the problem in his own way, and for more than 100 years, the Chepstow and subsequently the In spite of their apparent rivalry, Brunel and Stephenson were great personal friends, to the extent that they supported each other professionally. The new railway line, and bridge, had the effect of reducing the journey time between London and Swansea from 15 hours, by rail, road and ferry, to 5 hours by rail. Thus on that side, there was nowhere for an abutment capable of either resisting th The line between Chepstow railway station and Swansea was opened on 18 June 1850, and on 19 September 1851 the line was completed between Gloucester and a station east of the river, known as Chepstow East. Brunel, characteristically, sought a radical solution. In the 1950s, the speed of trains using the bridge was restricted to 15 miles per hour, because some of the girders had become distorted.

The span would have to be self-supporting, since although the Gloucestershire side of the river consists of a limestone cliff, the Monmouthshire side is low-lying sedimentary deposit subject to regular flooding. He was also present to provide Stephenson moral support, when the great Britannia box-girders were floated across the river prior to being jacked up to their final positions. So when it came to the revolutionary design at Chepstow, The Times of 24 February 1852, reported that 'Mr Stephenson, the eminent engineer, has examined the (great railway) bridge (at Chepstow) and concurred in the plan adopted by Mr Brunel...'. Nevertheless, Brunel's Chepstow bridge was a watershed, leading to a final refinement of the design in his great masterpiece, the Instead of hanging the chains from towers and suspending the bridge deck from them, Brunel used the chains to stress and slightly bow the tubes, which were braced against the chains using struts. This was the same year as Stephenson's tied-arch High Level Bridge at Newcastle upon Tyne, which was supposed to have influenced Brunel at Chepstow.
