Redbridge Causeway is a vital transport link between the city of Southampton and the west, as well as other key destinations. The scheme to fully refurbish the causeway is expected to cost £25 million.
Funding to enable completion of critical maintenance to the structures at the causeway, has been secured thanks to a successful bid by Hampshire County Council to the Department for Transport (DfT). The £13.4 million award will ensure Phase 3 of this major refurbishment scheme can be completed. Hampshire County Council is contributing a further £4 million to the funding.

Milestone Infrastructure will carry out repairs to the causeway’s defective concrete before installing an impressed current cathodic protection system (ICCP) to protect the structure from deterioration due to tidal and saltwater conditions.
Dyer & Butler will be providing Milestone with engineering assurance support to ensure Network Rail’s safety standards are met where work will affect the flyover across the railway during the completion of this contract.
The project involves working on three eastbound bridge structures spanning the two channels of the River Test.
Milestone Infrastructure will install a new waterproofing system on the bridge as well as upgrading a section to allow for a city-wide designated cycle route in the future.
The Redbridge Causeway site is adjacent to endangered habitats and the project has been designed to ensure their protection in collaboration with Marine Management Organisation and the Environment Agency.
These upgrades will increase the structure’s lifespan by 60 years and have been designed to cause minimal disruptions to the 60,000+ vehicles that use the Causeway each day.
