M27 Romsey Road bridge replacement scheme

The bridge which carried the A3057 Romsey Road over the M27 was constructed in the 1970s and was developing issues which meant it was nearing the end of its life. As a result, we have built a replacement and demolished the defective bridge.

Start date April 2018

End date March 2020

Cost £19 million

New bridge opens

We successfully opened the new bridge to vehicles and pedestrians on 5 December 2019. The bridge is also carrying the new electricity, gas and telephone connections we installed under the footways and the connections on the old bridge were cut prior to demolition. We successfully demolished the eastern half of the old bridge during a weekend closure in early February.
