Ground investigations are to begin between Dalraddy and Slochd as part of the £3 billion A9 Dualling programme.
Work to discover vital information on existing ground conditions in the vicinity of the carriageway will start on Monday, 13 February. The scheme will take seven weeks to complete.
A spokesperson for Transport Scotland said the project is the latest phase of ground investigations taking place along the route.
"This ground investigation is needed to get vital information on the existing ground conditions in the vicinity of the A9 carriageway between Dalraddy and Slochd as we progress our plans to dual the road," they said.
"We apologise for any inconvenience these works will cause and would thank road users and local communities in advance for their patience over the next few weeks. The contractor will closely monitor the operation of the traffic management measures to ensure that delays are kept to a minimum."
Traffic management arrangements include short, alternate single file traffic sections controlled by temporary traffic signals.
