Rush-hour traffic delays are expected for two weeks on A57 Carholme Road, the main commuter gateway to Lincoln from the west.
From February 14, Anglian Water will install a new water mains supply to the Stamford Home development on the former E2V site.
Known as Oasis, the development will create 189 houses and 66 apartments on the former manufacturing site off Carholme Road.
Starting February 14, work starts from former E2V site and will head down Carholme Road, moving towards the Grandstand. Two-way traffic will be operating at this stage.
From February 21, work should continue nearing the Pegasus crossing, where it will be crossing Carholme Road. Two-way traffic lights will be in use during this point.
Then, from February 28 work moves to Long Leys Road and heads towards Oakleigh Drive. This again will require two-way lights.
Lincolnshire County Council said at a later date, Anglian Water will link these two sections by working their way across the West Common.

John Clare from Anglian Water said: “When new homes are built the water company has a duty to make sure there is enough water to supply them.
“At the moment the mains in this part of Lincoln will not be able to carry enough water to serve the new development off Carholme Road.
“The developer, Stamford Homes, have asked us to make improvements which is what these works are about.”
Clare added: “Carholme Road is a busy route and we know this work is likely to inconvenience people whatever measures we take to reduce disruption.
“We are sorry for any inconvenience and would like to assure people we will do all we can to finish quickly with the minimum of disturbance.”
The scheme will also see a new length of water main installed under Long Leys Road between February 28 and March 25 and another across Carholme Common between the dates of March 14 – 25.
Works will be fenced off and the footway across the common will remain open to allow public access.
