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.

Project information


The M27 is a key strategic route which runs between Southampton and Portsmouth in Hampshire. It carries traffic to and from the West Country, along with heavy volumes of freight for the port and passengers for the cruise ships in Southampton.

The M27 is heavily congested at peak times all the way between Southampton (junction 3) and Portsmouth (junction 12). The M27 near Southampton also joins with the M3 which is the only motorway between the south coast and London.

The aims of this scheme are to:

  • replace the current deteriorating bridge with minimal disruption to road users
  • improve safety for our customers
  • re-establish a key transport link and remove the temporary weight restriction
