This project was to install two walkways under the M27 bridge over the river hamble in Hampshire.

These walkways will allow the Highways agency to inspect the bridge bearings without the need to wait for the correct tidal conditions, and access the bridge by boat. The walkways are now accessed from the hard shoulder of the motorway, via a removable access platform.

The main span of the bridge was replaced following a bridge strike.

The new 28 metre bridge section was fabricated at our works, and transported to site on a special rear wheel steering trailer, to enable it to negotiate corners.

The lifting operation took place at night to minimise traffic disruption, and lasted just 7 hours.
