Essential maintenance on the A82 Fort William to Inverness road, at the Fort Augustus Swing Bridge, is scheduled to take place on Tuesday for one night.
The project will involve essential mechanical maintenance including replacing some of the technical components, which are vital to ensure the swing bridge continues to operate effectively when opening and closing across the Caledonian Canal.
The overnight project will take place between 9pm and 6am for one night with all works expected to be completed by 6am on Wednesday.
To ensure safe access to the components, the bridge will need to be swung open resulting in the full closure of the A82 at Fort Augustus Swing Bridge.

A diversion route using the A87 and A887 will be sign posted from Invermoriston and Invergarry for both northbound and southbound traffic. All traffic management will be removed during the day.
The diversion route will add approximately 20 minutes onto journey times. There will be local access only on the A82 to Fort Augustus.
Commenting on the essential maintenance, Eddie Ross, from BEAR Scotland said: “These essential bridge maintenance works will help ensure the bridge continues to function safely for years to come.
“The traffic management is essential to keep everyone safe during the project. We have planned the essential works to take place overnight to minimise disruption for road users however, our teams will do all they can to complete the works as quickly and safely as possible.
