The long-mooted Broughton bypass will come before Preston City Council’s planning committee on September 2.
However, although the authority is a consultee on the major scheme, the final say will fall to Lancashire County Council (LCC) later in the year.
A city council spokesman said: “It’s the county council’s application.
“Our planning committee is being asked for its response and to agree what that is at the meeting.”
LCC highways chiefs say the bypass is needed to help cut congestion on main roads to the north of Preston.
More than 22,000 journeys are made through the area on the A6 on an average day, leading to bottlenecks.
They have resubmitted plans for the scheme following a series of packed meetings with residents in Broughton, Fulwood and Goosnargh last month, to discuss the details of the project.
However, some residents fear the bypass will simply move congestion from one part of the area to another.
Work is also currently underway to upgrade the Broughton roundabout, which links the village to Preston, the M55 and junction 32 of the M6.
Motorists have been warned the work has been scheduled until the end of the year.
The city council planning meeting will take place at Preston Town Hall from 10am on Monday September 2.
