Drivers and Fulwood residents are being warned of delays as a six-month long series of roadworks begins.
Two extra lanes are being added to Junction 31a of the M6 where it joins Bluebell Way and new traffic signals added to the roundabout.
Three roundabouts on Eastway, Olivers Place and Sherwood Way, and Pittman Way and Andertons Way will be widened as part of the scheme.
Lancashire County Council are doing the work from 6 June 2012 to ready the roads for an anticipated increase in the population of the Northern area of Preston as the population of Central Lancashire continues to boom.
Paul Dunne, highways manager for Preston, said: “North Preston is a developing area and the Homes and Communities Agency, on whose behalf we are carrying out this project, has identified the need to invest in increasing the capacity of existing roads to minimise future congestion.
“We would be very grateful for people’s patience while these improvements take place over the coming months.”
Works to the three roundabouts will not take place during peak times (7am to 9.30am and 3.30pm to 6pm) but outside of these times lane closure and traffic signals will be in place.
The motorway slip road work at Bluebell Way will take place from 8pm to 6am and it will be restricted to one lane during this time but for two weeks in October the slip road will be closed completely and a diversion put in place.
The work is due to be completed by 19 January 2013.
