Residents are being urged to give their views on the dualling of the A9 Inverness-Perth road at a special drop-in session tomorrow.
Designers Atkins Mouchel Joint Venture will be at Tomatin to speak to the public about the proposals to upgrade the section of the route between the village and Moy.
The new road will follow the path of the existing single carriageway.
It will also fill the gap between two stretches of dual carriageway from Inverness-Moy and Tomatin-Carrbridge.
The section passes Dalmagarry Quarry, which was searched twice for the body of Inverness mother Renee MacRae and her three-year-old son Andrew.
The pit beside the A9 became the focus of the huge police investigation into the mysterious disappearance of the housewife and her son.
The pair vanished nearly 40 years ago – and what was initially a missing persons inquiry became a murder hunt.
Mrs MacRae’s burned-out BMW was found in a layby beside the A9 and a bloodstain was discovered in the boot.
The Scottish Government has committed to dualling the notorious trunk road from Perth to Inverness by 2025 at a cost of £3billion.
Tomorrow’s drop-in session is offering people the chance to speak to the designers on an informal “one-to-one” basis.
It is being held at Strathdearn Village Hall at Tomatin, from 3pm-7pm.
Members of the public are being asked to tell the firm about any details they think are relevant to the development of the road.
An Atkins Mouchel spokesman said: “The current stage of appraisal includes information gathering and assessment studies.
“The drop-in session is therefore primarily intended to outline the scheme development, provide details of forthcoming studies along with the programme, and gather local information.”
The firm, which won the design contract for the whole of the northernmost section from Dalraddy-Inverness, will also be staging consultations with affected landowners over the coming months.
Further exhibitions about the Tomatin-Moy scheme and the Dalraddy-Slochd scheme are planned in the next few months.
Elsewhere tomorrow, an exhibition about the plans for dualling further south starts at Dalwhinnie.
The event will be held at Dalwhinnie Village Hall from 3pm-8pm, and again on Wednesday from 11am-4pm.
