The bridge over the River Witham on Dixon Street in Lincoln will be closed for at least 12 weeks of refurbishment works this summer.
Work on the bridge between Dixon Way and Witham Court is expected to begin on Monday, July 23.
However, Lincolnshire County Council has warned that repairs could take longer depending on the level of deterioration revealed when the outer layers of concrete are stripped back.
The works will include:
- The replacement of the concrete coating on the underside of the structure
- Renewal of the waterproofing on the bridge deck
- Resurfacing of the carriageway
- An upgrade to the pedestrian crossing next the bridge
The bridge will be closed to traffic for the duration of the project, with traffic diverted via Tritton Road, Ropewalk, St. Mark Street and High Street.
Pedestrian access over the bridge will be available at all times, and the path alongside the River Witham also will remain open.
Andy Antcliff, senior engineer, said: “The bridge is in poor condition and needs of a lot of work.
“By taking action now, we can stop it deteriorating further. If we just leave it, we would eventually need a new bridge, which would be a far more costly and disruptive project.
“We realise this is a busy route, so we’ll be doing as much of the work as we can during the school holidays, when traffic is much lighter.
“And the team will be working extended hours during evenings and weekends to get it done as quickly as possible.
“However, despite our best efforts, there will inevitably be some disruption and we apologise in advance for any inconvenience caused.”
