The Scottish Government has published a £60bn infrastructure plan of 80 construction projects, with 54 for road and rail.

Schemes to safely maintain the road network include upgrading the A82 and route action programmes where there is a higher than average accident rate.

The government has revealed plans to invest in new roads, including the Aberdeen Western Peripheral Route, dualling of the Balmedie to Tipperty road, and completion of the M8 between Newhouse and Ballieston.

The plan revealed that the trunk road network is 3,405km long, and the increasing backlog of structural and bridge maintenance schemes would require an additional £713m.

The government has also said that securing the necessary consent for the upgrade of the A9 between Perth and Inverness to dual carriageway standard by 2025 will be a major part of the programme.
