Work has begun on a £1 million project to refurbish Newhaven Swing Bridge which forms part of a key coastal route through the county.
The project will see a complete revamp of the original mechanical and electrical components on the bridge which carries the A259 over the River Ouse.
The East Sussex County Council scheme is expected to last until May but the authority says the work will have little effect on motorists or marine traffic. A small number of night time closures may have to be imposed on the bridge later in the project but these will be advertised well in advance.
Cllr Carl Maynard, county council lead member for transport and environment, said: “The reliability of the swing bridge is of paramount importance, both to allow traffic to flow along the main coastal route and for the smooth operation of Newhaven Port.
“The bridge is 40 years old and while it is rigorously maintained, the electrical and mechanical systems are outdated and need replacing. This project, which will have a minimal impact on road and river traffic, will bring the bridge into the 21st century and ensure it continues to operate reliably for many years to come.”
Last autumn the bridge opening mechanism was inundated by a tidal surge, leading to several weeks of inconvenience while repairs were carried out. The new controls have been designed to be more robust, the council said. The work is being carried out by contractors AMCO Engineering.
