Ground investigation works at A9/A82 Longman Junction
The work is expected to last around four weeks and the vast majority of it will take place off the line of the existing junction, ensuring the need for traffic management is kept to a minimum.
A Transport Scotland spokesperson said:
"This ground investigation contract is vital to inform the ongoing design and assessment of the improvements to this strategic junction in the Highland capital having let the public see and comment on developing options for the scheme in May.
“Although the vast majority of the work is located away from the existing road network, investigative work is required in close proximity to the live carriageway. We would thank road users and local communities in advance for their patience during any short duration traffic management operations which may be required to ensure safety of the public and workforce during these elements of works.
"The contractor will closely monitor the operation of any traffic management measures to ensure that any delays are kept to an absolute minimum. We would ask drivers to plan their journeys in advance using the Traffic Scotland website, Twitter feed or Traffic Scotland radio.”
