A contractor has been selected to take forward ground investigation work as part of the A82 Tarbet to Inverarnan improvement scheme in Scotland.
Transport Scotland has announced the award of a ground investigations contract for over £370,000 to Environmental Scientifics Group.
The work is programmed to start in October and is expected to be on site for a period of nine weeks.
The work is part of the stage two assessment for the route and it is expected that a preferred route alignment will be identified by next Summer.
Transport Minister Keith Brown said: “We are firmly committed to upgrading the A82 between Tarbet and Inverarnan.
“We announced earlier this year that any upgrade work would take place along the line of the existing 17km section of the route. Now we are taking forward further design work to identify a preferred route by next summer.
“These ground investigations due to get underway next month will provide the detailed information needed to help inform the scheme’s design.
“We need to ensure that any future upgrade fits within the area’s outstanding landscape and environment and maintains the renowned beauty of the Loch Lomond and Trossachs National Park. The work we are doing along this vital route that connects the Highlands and Islands with the central belt will lead to improved road safety and journey time reliability and meet the needs of business, communities and visitors alike.”
