A section of Millgate will be closed from Monday as part of work to overhaul Newark’s waste and water network.
A stretch of the road from Victoria Street to Southfield Terrace will be shut until June 19 as Severn Trent builds a reception shaft for its tunnelling machine – known as the Siege Breaker – to be lifted out.
The machine was lowered into place in August, at Crankley Point. It moves around 15-20 metres a day and, when finished, will have created a tunnel nearly three kilometres long and large enough for a Transit van to drive through.
Motorists can still access Millgate via Southfield Terrace.
The firm said it would be speaking to all residents in Millgate about the work, ahead of a general exhibition.
The overall project will see more than 400 homes and businesses protected from sewer flooding, as well as future-proof water supplies, when it is completed in 2020.
BNM Alliance is carrying out the work for Severn Trent.
