Motorists have been warned of disruption during works on the A9 dualling programme.

From Monday, July 11, a stretch of the route between Tomatin and Moy in the Highlands will be reduced to single file traffic sections with temporary traffic lights in place.

The roadworks are for ground investigations around the £3bn project to upgrade the A9 to a dual carriageway between Perth and Inverness.

Transport Scotland said on Monday that the road restrictions would last around seven weeks and would involve work would be carried out beside the carriageway.

A spokeswoman said: "This ground investigation is needed to get vital information on the existing ground conditions in the vicinity of the A9 carriageway between Tomatin and Moy as we progress our plans to dual this section of the route.

"We apologise for any inconvenience this 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."

Twelve sections of the A9 are being dualled as part of the project, which is hoped to be completed by 2025.

The first stretch of the road to be revamped - between Kincraig and Dalraddy - is expected to open next summer.
