Transport Scotland has awarded a £92m highways contract to Amey.
The six-year contract will see Amey maintain and improve more than 550 miles of road in South East Scotland, including Edinburgh’s city bypass.
Transport minister, Keith Brown, said: 'Our motorways and A class roads are fundamental to Scotland’s economic well-being as we need well maintained routes, with reduced congestion and reliable journey times to allow the transfer of goods and services.
'This contract will result in the high quality and value for money trunk road maintenance service that our communities and businesses expect.'
The contract, which is subject to up to two one-year extensions, includes the design and delivery of major road and bridge maintenance work, road inspections, salting, snow clearing and the repair of motorway lighting and traffic signals.
