Both Pelham Bridge and Canwick Road in Lincoln will be closed for 13 consecutive nights, as further road improvement works are carried out.
There are 10 weeks to go before the £4.5 million Canwick Road project is complete, bringing an extra lane and traffic improvements to the area.
A new stage of the works is due to start on April 7, include re-cabling the tidal flow gantries and variable message signs on Pelham Bridge and Canwick Road.
Lincolnshire County Council says the existing cables are decades old and have reached the end of their service life.
To enable this work to go ahead, highways teams will be working overnight between 8pm to 6am from Tuesday, April 7 through to Sunday, April 19 (inclusive).
Pelham Bridge and Canwick Road to be closed between South Park Avenue and the north side of Pelham Bridge during these times. Traffic will be diverted via St Mary’s Street, High Street and South Park Avenue.
During the overnight closures the right turn from South Park Avenue on to Canwick Hill towards Washingborough Road will be reinstated.
Northbound movements will be allowed when turning left out of Portland Street on to Pelham Bridge back into town only.
Access will be maintained for residents within the closure and a lane will be open to emergency vehicles only. Pedestrian access will be maintained as normal.
Alan Aistrup, special projects manager at the county council said: “We don’t expect these overnight closures to cause significant disruption to road users, but we advise motorists to allow some additional time for their journey.
“We will also use the opportunity of these closures to improve areas of the road surface along the tidal flow and facilitate works required on the East West Link Road project.
“I’d like to thank the public for bearing with us during these works. We’ve made good progress so far, and are on schedule to complete the Canwick Road improvements by the end of May, which will greatly benefit road users in and around Lincoln.”
