The proposals for the dualling of the A96 Inverness-Nairn will essentially create a new road along the Moray Firth coast.
Transport Scotland’s plans will involve the creation of six grade separated junctions and a new Nairn bypass.
Starting from Inverness, new junctions will be built at Smithton and Newton at Balloch.
The road will run to the south of the existing route before crossing to the north at Kerrowaird.
A major new junction will be built at Mid Coul, near Inverness Airport, before the road crosses farmland land to rejoin the current route at Gollanfield, near the well-known Highland Foodstop restaurant.
The next new junction will be to the west of Nairn before the road swings away to the south of the town and across fields.
Some local roads will be realigned in order to create flyovers across the new dual carriageway.
A new bridge over the River Nairn will be built at Broadley.
Other changes include the removal of a series of bends on the A939 Nairn-Grantown road, south of Househill.
From there the road will cross land at Blackpark farm and head towards Auldearn.
The Nairn bypass ends at a new junction on the outskirts of Auldearn.
The A96 will continue to the north of Auldean and the existing route.
It will sweep through land at Penick and rejoin the current A96 east of Wester Hardmuir farm.
Transport Scotland claims that one of the major benefits will be a reduction in journey times between Inverness and Aberdeen.
