Next stage of Redbridge repairs scheduled for January 2020

Hampshire County Council has appointed Skanska to carry out the next stage of repair work on the Redbridge Viaduct. Work is scheduled to begin on 6 January 2020

Dec 9 2019

Consisting of four concrete bridges, Redbridge Causeway is a key access to the Port and City of Southampton from the West, carrying freight and commuters over both the River Test and the Southampton to Romsey railway line. It is the only direct route for pedestrians and cyclists to cross the River Test.

This is the second part of a three-stage project to refurbish all four structures carrying the A35 Redbridge Causeway, and follows the first phase of repair works which were completed in 2018. 

This package of works will involve repairs to the concrete under the bridges which will be undertaken in phases and will take approximately 18 – 20 months to complete. The works are highly weather dependant, and will include works to:

  • Redbridge Viaduct, which carries the A35 Westbound carriageway between M271 Redbridge Roundabout and Totton,
  • Redbridge Road bridge which carries the A35 Eastbound carriageway over Test Lane/Old Redbridge Road, Southampton.

The concrete repair work will protect over 100 supports of the Redbridge Viaduct and Redbridge Road bridges. It will be carried out in a sequence of removal and localised patch repairs in order to avoid the need for temporary propping and carriageway closures of the road above. A cathodic protection system will also be installed to effectively prolong the life span of the existing structures.

Redbridge Viaduct is a 50 year old 270m long structure 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 concrete supports.
