The latest designs for the Cross Tay Link Road will be unveiled to the public next month.
A series of consultation events will be staged to give residents the chance to comment on the £113 million project, before a formal planning application is submitted later this summer.
The long-awaited scheme aims to cut city centre congestion and reduce pollution levels, by linking the A9 with the A93 and A94 north of Scone.
There has been controversy over the rote, which will cut through a new 700-property housing estate.
Sweco UK, which was appointed lead consultant on the project, will host events at Luncarty, Scone, Coupar Angus and Perth. Feedback will be used to draw up a finalised plan, which is expected to be considered by councillors in the coming months.
The project involves a new bridge over the River Tay – and the Perth to Inverness train line – as well as a realignment of part of the A9 and a new junction north of the Inveralmond roundabout.
The latest designs will show new roundabouts at Highfield Lane and on the A93 and A94, plus a “green” bridge at the Highfield Plantation.
Sweco hopes to include new and improve cycling and walking infrastructure along the length of the route.
Last month, councillors rejected alternative plans for the road, despite growing concern about the health impact on people living in the planned Scone North housing estate.
Scone and District Community Council suggested a “northern route” that would bypass the new estate, and prevent traffic from driving past residents’ homes.
But local authority officers argued that changing the route at this late stage – after several years of planning – would lead to a costly 17-month delay.
The Bridgend, Gannochy and Kinnoull Community Council recently questioned the effectiveness of the new road.
At a public inquiry exploring congestion around Bridgend, vice-chairman David Beattie said: “In deciding the impact of the CTLR, you have to look at what level of traffic that is currently using the road, will stop using it because there is an alternative route.
“Our view is that we would like to see this project established and tested, before we start saying: This is great, Bridgend has been solved.”
Dates for next month’s four consultation events are pencilled in for between August 21 and 28, but have still to be confirmed.
