Councillor Rob Humby, Deputy Leader and Executive Member for Economy, Transport and Environment at Hampshire County Council, explained: “Our teams are working hard to keep this key access route open to all traffic, repairing over 100 concrete supports under the Redbridge Viaduct. Those travelling over the bridge may not notice the extent of the work going on underneath them and the efforts being made to limit disruption to those travelling on this busy road. I was pleased to see for myself recently how well the work is progressing, how the unique marine environment is being protected while the repairs are carried out, and how stringent Covid-safe measures are in place for all those working on site.”
Redbridge Causeway, a deteriorating set of concrete bridges over the River Test that carries 60,000 vehicles a day, has been identified as a high-priority road improvement scheme in the South East for Government funding.
Councillor Humby continued: “Redbridge Causeway is a key link between the Port of Southampton and the western side of Southampton Water. It carries freight and commuters over both the River Test and the Southampton to Romsey railway line, and is the only direct route for pedestrians and cyclists to cross the river.
“It is an essential route not only for the local economy but also for import and export business affecting the whole of the country. We have put in a bid for national funding for the repairs Redbridge urgently needs in recognition of its importance to the UK economy, particularly at this crucial time for business following the Coronavirus outbreak and as we head towards the UK’s exit from the EU.”
Works on the Viaduct are being carried out under tidal conditions, and in a sequence which limits the need for temporary propping, and therefore any lane closures on the road above. The next stage of work will include the installation of a cathodic protection system which will prolong the lifespan of the structure by applying a low voltage electrical current to the steel reinforcement inside the concrete supports, thereby reducing the likelihood of further corrosion and degradation.
