Ground investigations at A83 Rest and Be Thankful continue

Road users travelling on the A83 at the Rest and Be Thankful are advised that essential ground investigation work currently being undertaken in the area will require traffic to be diverted onto the Old Military Road (OMR) between 8am and 6pm on 7 and 8 July, and 14 and 15 July, as the essential work continues on the hillside above the A83.

These diversions are required during daylight hours to ensure the safety of the workforce which means the work cannot be done at night.

Transport Scotland appreciates the frustration that traffic management, including diversions onto the OMR causes the local community, businesses and road users. As we carry out any works, we are committed to ensuring that Argyll & Bute remains open for business.

The works will involve large cranes, ancillary equipment and a large number of personnel to lift specialist drilling equipment on to the hillside. During these works these large cranes will be required to occupy the full width of the A83 carriageway.

These temporary diversions onto the OMR are key to maintaining safety for both road users and the workforce.  We will work with the ground investigation contractor to complete the work as quickly as possible and to reduce the number of diversions needed, if feasible. Transport Scotland would like to thank local communities and road users for their cooperation.
