The preferred route of the most northerly section of the A9 to be dualled in the current scheme will be revealed later this month.
Transport Scotland will set out their plans for the Tomatin to Moy section of the north’s busiest road on November 14.
The section is just over five miles in length and will plug the gap between the existing dual carriageways from Inverness to Moy and Tomatin to the Slochd Summit.
It is the most northerly to be dualled in the current £3billion project.
Ground investigation work was carried out earlier this year and public consultations will now be held giving the outcome of the route assessment work as well as revealing the preferred route of the road.
The A9 is largely being dualled along the route of the existing road and it is expected that work on the Tomatin to Moy stretch will mainly involve widening the road along its northbound side.
Main junctions have also under consideration north of Tomatin and both north and south of Moy.
The section is one of three to go out to public events in the next few weeks, including the Dalwhinnie to Glen Garry section which straddles the boundary between the Highlands and Perthshire.
A Transport Scotland spokesman said: “The work to dual the A9 between Perth and Inverness continues apace and over the next few weeks we are holding a series of public engagement events to let locals and road users see and comment on the preferred routes for three more of the dualling projects including the section between Tomatin and Moy.
“We would encourage anyone with an interest in any of these projects to come along to see our proposals and comment on them.”
The Tomatin to Moy public consultation will be held on Monday, November 14 between 3pm to 8pm at Strathdearn Village Hall in Tomatin.
A second event will be held the following day at the same location between 11am to 8pm.
Meanwhile the preferred route will also be revealed for the 7.5mile Dalwhinnie to Glen Garry section which runs through the Drumochter Pass.
The section is constrained by the geography of the area as well as the Beauly-Denny powerline and the Highland Mainline railway track.
This consultation event will take place on Wednesday, November 23 between 12pm and 7pm at Dalwhinnie Village Hall.
