Castle Road will be shut to traffic at its junction with Haugh Road to the junction with Bridge Street between 0900 and 1700 BST.

Highland Council said an alternative route for drivers will be available using Bridge Street, High Street, Castle Street and View Place.

Vehicle access to businesses on Ness Bank will be via Cavell Gardens.

However, the temporary closure will not affect normal access for cyclists, pedestrians and emergency vehicles.
