Four years. £30 million. One historic bridge.

Network Rail completed its major restoration in December 2023. The programme replaced or restored decayed timber and metallic elements while retaining the bridge's historic appearance.

Network Rail says two 160-tonne metallic spans were installed during the final phase and the restored viaduct fully reopened in December 2023.

Conserving a working bridge

More than replacing the metalwork

The restoration had to address the timber structure, metallic section, railway track and public walkway together. Heritage conservation and everyday operation were both central: the bridge needed to retain its appearance and continue to serve its communities.

Preparing the span movement

Network Rail reports a trial on a purpose-built mock track before the new spans were transferred. Old metalwork was taken away using pontoons, and gantry hoists raised and lowered components. Work over tidal water required careful handling as well as access for the workforce.

The railway and path

Network Rail’s project summary records 120 metres of new walkway with stainless-steel handrails, and 297 metres of renewed track on the northern side. Moving the spans used 44 jacks and six rail trailers. These figures describe particular parts of the works, rather than the length of the whole bridge.

What “like for like” means

In this context, renewal retained the bridge’s familiar form while replacing deteriorated components. A historic bridge can remain recognisable through substantial repair. Its significance lies in its design, setting and continuing use, as well as the fabric that survives.
