Transport Scotland has said that ground investigation work for the upgrade of the intersection between the A9 and A96 between Inshes and Smithton is to get under way today.
Causeway Geotech was awarded the contract for the scheme that involves construction of a new single carriageway in February.
Work on site is expected to take seven weeks and will be mostly carried out off line from existing roads.
A Transport Scotland spokesperson said: “This ground investigation contract will help inform the design work for this new link road in the Highland capital having identified the preferred option last October.
“Although the vast majority of the work will not require any traffic management, a small fraction of investigative work will take place on the carriageway of roads in the area. We would thank road users and local communities in advance for their patience during any short duration traffic management operations which may be required as the works progress.
“The contractor will closely monitor the operation of the traffic management measures to ensure that any 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.”
