As part of the ambitious A9 Dualling programme, ground investigations on the stretch of the route between Pitlochry and Glen Garry are due to begin on Monday 4 September.
Although the vast majority of the work, which is expected to last around 30 weeks, will be carried out away from the existing road and will not require traffic management, some traffic management measures will be required when necessary to allow work beside the carriageway to be carried out safely.
This will include alternate single file traffic sections controlled by temporary traffic signals.
A Transport Scotland spokesperson said:
“This ground investigation is needed to get important information on the existing ground conditions in the vicinity of the A9 carriageway between Pitlochry and Glen Garry as we progress our plans to dual the road. This is the latest in a series of ground investigations taking place along the route.
“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 months. The contractor will closely monitor the operation of the traffic management measures to ensure that delays are kept to a minimum.
“While we do not expect major disruption to traffic, we would ask drivers to plan their journeys in advance using the Traffic Scotland website, twitter feed or Traffic Scotland radio.”
