A consultation is under way on plans for the Preston Western Distributor and East West Link Road.
The scheme includes a new road linking Preston and southern Fylde to the M55, and two new roads connecting to housing areas in north-west Preston and Cottam.
This consultation is part of preparations for a planning application expected to be submitted in March.
The proposals will help to promote new housing and business development in the area, while increasing capacity on the existing road network.
Lancashire County Council’s consultation runs until February 12 and includes public exhibitions for people to find out more about the plans.
The events run from 10am to 8pm at: Preston Grasshoppers on Wednesday, January 13 and Wednesday, January 20; and at Ashton and Lea Golf Club on Monday, January 18.
People can also complete a questionnaire at www.lancashire.gov.uk/haveyoursay.
The county council has written to around 8,000 residents in the area to ask their views.
The scheme has funding from central government, via the Preston, South Ribble and Lancashire City Deal.
County Coun John Fillis, cabinet member for highways and transport, said: “We’re pleased that the public will get the chance to help to shape these plans, which will bring about housing developments in this part of the city.
“Following this consultation we will consider your comments to see if any improvements could be made, before the planning application is made later this year.”
The proposed Preston Western Distributor is a 4.3km dual carriageway linking the A583 at Lea to the M55 at Bartle with a new motorway junction.
The East West Link Road would be a 3.4km long single carriageway road linking Lightfoot Lane to the Preston Western Distributor.
As part of the Preston Western Distributor, a link road will be created to Cottam Way. The Cottam Link Road will join the Preston Western Distributor north of the Lancaster Canal.
It is hoped the road will also help kick-start activity on the enterprise zone on BAE’s site in Warton which so far has created just five jobs, by improving transport links to the Fylde coast site.
