Work started in June to re-waterproof the 60-year-old bridge in Lincoln; the end of the works is now in sight.
To carry out the work, teams had to completely strip the bridge back, removing the kerbs, streetlights, paving slabs, road surface and scrape off the old waterproofing.
High-power water jets were used to break away old and substandard pieces of concrete on the bridge deck, in a process called hydrodemolition. These areas were then repaired before the new waterproofing was applied.
As senior bridge engineer, Richard Waters, explains, the bridge was in a poorer condition than the team expected.
"There have been a lot more concrete repairs to the bridge deck than we hoped for, and getting them all repaired pushed back the start of our waterproofing.
We have also had to use a more complex expansion joint which requires extra work, and found some of the street lighting columns have corroded badly and need strengthening before they can be put back up.
"We couldn't have known about the extent of these issues until we stripped back the bridge, but it shows how necessary these repairs were", he said.
The extra repairs and expansion joint work has extended the overall scheme by around a week. The bridge is now expected to reopen to traffic and pedestrians on Sunday 22 August.
Resurfacing work on Canwick Road leading up to the bridge will also be complete, and the tidal flow will be in operation again from Monday 23 August.
Cllr Richard Davies, executive member for highways at Lincolnshire County Council, said:
"I'd like to thank residents in Lincoln for their patience whilst we did these repairs on Pelham Bridge. I know the closure has caused disruption in the city, and I'm glad the end is now in sight.
"It's a shame that the extra work required has extended the closure, but I'd rather we do the job right this time, and avoid us having to come back with a huge job like this for many years. We'll also still be off the bridge well before the schools start back again in September."
