Bonar Bridge Repainting To Be Discussed At Economy And Infrastructure Committee

12th November 2024

Bonar Bridge will be discussed at the Economy and Infrastructure Committee of Highland Council on 14 November 2024.

Bonar Bridge had a paint inspection carried out in 2016, which stated that the paint system had largely failed and should be replaced within 5 years. The form of the structure is prone to sudden collapse if not adequately maintained.

The structure is not currently a high risk for closure or restriction, this scheme is required to prevent a much larger repair bill in the future.

Potential Consequences
Bonar Bridge has a high strategic function on the Sutherland road network. It is one of only two bridges connecting East Sutherland and Caithness to the south. The other (A9 Dornoch Bridge) can be closed due to high winds. The form of the structure is prone to sudden collapse if not adequately maintained. This is one of our largest bridges, and therefore the cost of replacement will be very high (est. £30m).

Proposed Scheme
Blast clean and repaint the entire structure. Minor repair works where required. Improve drainage around bearings. Remove redundant and unsafe access gantry.

Proposed Scheme Cost (£k)
£1,425k
