This June a contraflow system will be installed on the A14 Orwell Bridge, which carries more than 60,000 vehicles a day across the River Orwell in Suffolk, so that two joints can be replaced on the westbound side of the structure.
The work is expected to be completed in August and will see traffic sharing the eastbound carriageway, with one lane in use in each direction.
National Highways said that the old bridge joints weigh around 7.5 tonnes each: 'It’s a delicate operation that requires sustained working and access to the structure', the English strategic roads operator said.
The current joints were installed in 1998 and are reaching the end of their life. They will be replaced with ones which are 'designed to last for 50 years,' National Highways said.
Bridge joints are crucial components that essentially provide a flexible connection between bridge sections, allowing for movement and expansion of the bridge structure due to factors such as temperature changes, shrinkage and traffic loads.
Martin Fellows, National Highways regional director for the East, said: 'This maintenance work is vital in helping to ensure the long-term safe operation of the bridge. We understand the impact that any reduction in capacity on the Orwell Bridge can have on those who rely on this iconic and important piece of road infrastructure.
'A range of options to carry out these essential works were considered. We have worked closely with Suffolk County Council, the police and many stakeholders and have agreed that using a contraflow system during the roadworks was the least disruptive for road users, local communities, businesses and others who depend on the bridge on a daily basis.'
A plan is also being developed to replace two eastbound joints in the near future.
'Any full bridge closures will take place overnight when roads are less busy, and these are being kept to a minimum,' National Highways said.
Further details, including a confirmed start date, will be communicated in the coming weeks.
