A Boston road bridge will now be closed for repairs until early November after more areas of deterioration were uncovered.
The Boston Chain Bridge was supposed to reopen at the end of this month after sections of concrete were replaced and water mains upgraded.
To allow the work to take place safely, the road will be closed for the duration of the project, with traffic diverted via the A52 Swineshead Road, B1192 Holmes Lane, B1391 Ralphs Lane, B1397 London Road and West End Road, and vice versa.
Access will be maintained for pedestrians and cyclists.
The junction of West End Road with Chain Bridge Road and Old Hammond Beck Bank Road will remain open throughout, but will be controlled by three-way temporary traffic signals.
Vehicles will be unable to access the B&Q, Tesco, Downtown and Alban retail park from the east of the A52 roundabout, and customers will need to use the alternative route.
Andy Antcliff, senior bridge engineer, said: “We’re continuing to find significant amounts of defective concrete that need to be removed and replaced. It’s imperative that we get this done before reopening the road.
“Most of the repair works are underneath the bridge, so although it appears that the concrete deck is almost ready for the new surfacing that can’t be done until the deck and beams are back up to full strength.
“We now expect the project to be completed in early November.
“We apologise for the further disruption this will cause to motorists, and thank drivers for their ongoing patience while the team complete the works.”
