Latest updates

Hampshire County Council is pleased to announce that the main bridge joint repair work and surface replacement work on the A35 Redbridge and Totton Bypass, Westbound, is complete.

Following this work, Hampshire Highways is taking the opportunity to invest in the future and further secure the condition of this critical route by resurfacing the Eastbound carriageway.

The works will take place at night only, so as not to affect day time traffic.

Resurfacing work is currently scheduled to be carried out on the following dates, weather permitting:

  • Thursday 19 April to Friday 20 April from 8pm to 6am. And then Saturday 21 April at 8pm to Sunday 22 April 2018 at 6am and Sunday 22 April at 8pm to Monday 23 April 2018 at 5am
  • From Saturday 28 April 2018 at 8pm to Sunday 29 April at 6am and then Sunday 29 April at 8pm to Monday 30 April at 5am

Any changes to these dates due to unforeseen circumstances or bad weather will be updated on this web page as soon as they are confirmed.

Overview

Redbridge Viaduct is a 50 year old bridge carrying westbound traffic out of Southampton over Test Lane, the railway and the river Test. Due to its age, the harsh marine environment and the large volumes of traffic that use this bridge it now requires essential repairs to the joints and concrete supports. The viaduct is 270 metres long, supported on nine reinforced concrete piers and 106 columns.

Phase 1 of the bridge works, are now complete and involved replacing all 21 expansion joints between each span and the longitudinal that runs the entire length of the bridge, which, were leaking and causing water to run down the supports and columns underneath the viaduct.

Phase 2 of the work is now underway and will see the Eastbound carriageway resurfaced from Rushington roundabout to the Redbridge Causeway.

The final stage of the project is to repair the concrete supports underneath the bridge to avoid the need for reduced weight limits being imposed for traffic crossing the bridge. This work has been provisionally planned for Autumn 2018.

When the work is taking place

The nature of the works make them highly weather dependant and a decision whether to go ahead with the works will be made in the days preceding each of the dates below.

Phase 1 – February and March 2018

Complete

Phase 2 – March 2018 onwards

Resurfacing work will be carried out on the Eastbound carriageway from Rushington roundabout to the Redbridge Causeway starting in March 2018. This work will be undertaken under a full road closure on Saturday and Sunday nights for approximately three weekends (weather permitting). These works will not include any daytime closures.

As with the phase 1 works, signed diversions will be provided to cater for non-motorway and motorway traffic.

Phase 3 – Autumn 2018

The final stage of the project is to repair the concrete supports underneath the bridge to avoid the need for reduced weight limits being imposed for traffic crossing the bridge. This work has been provisionally planned for Autumn 2018.

Diversion routes

Signed diversions will be in place during the closures. The majority of drivers will use the diversion along M271, M27 and A326. For drivers who are not able to use the motorway the diversion will be via Romsey. The motorway diversion will increase travel by approximately 12minutes (8miles).
