The new plans propose a road been Cambourne and Dundnance Lane
Plans for a new road to help ease congestion between Camborne and Redruth have gone on display to the public.
The plans propose a new road between Dudnance Lane, near Pool, and the Dolcoath area of Camborne.
The road will link to Redruth via another new route from Dudnance Lane, which has already been approved.
Peter Swain, from Cornwall Council, said the road network was needed to relieve heavy congestion on the existing A3047 dual carriageway.
'Number of concerns'
The plans have been proposed by the Camborne, Pool and Redruth Urban Regeneration Company.
Camborne parish councillor Stuart Collimore, said: "I've got a number of concerns about it, particularly that it will actually lead to more traffic in Camborne and lead to more congestion in the town centre."
The proposed road will also provide access to a new housing development in Camborne.
John Stephens, who lives opposite the new housing site, said: "We were told it was going to cut down congestion outside our houses.
"It's not. We're still going to get the traffic. With the proposal of the housing estate opposite, we're going to have up to 400 houses."
The route will be built on brownfield and greenfield land. No houses will be demolished.
The plans are being displayed in various places along the proposed route.
Highways officials expect the proposals to be submitted in the next couple of days.
