Four "world-class" contractors are in the running for a £415 million motorway improvement programme.
Work is to be carried out to improve parts of the M8, M73 and M74 motorways.
When it is completed, drivers should benefit from shorter journey times and improved road safety.
The construction works include plans to upgrade the section of the A8 from Baillieston to Newhouse, completing the M8 motorway between Edinburgh and Glasgow.
Improvements to the M74 Raith interchange are also planned, along with the widening of key sections of the M8, M73 and M74.
Work is expected to commence late next year and should be complete by 2017.
The project is of a similar scale to the completion of the M74 motorway, which supported 900 construction jobs.
Four consortia have been selected to bid for the work - Scotia Roads Group, Scottish Roads Partnership, Connect Roads and Caledonia Roads Group.
Infrastructure and Capital Investment Secretary Alex Neil said he was "delighted to see such strong interest in this project from a host of world-class contractors".
He added: "Strong competition can only be good news for the taxpayer and we also know from our experience on our recent, successful M74 completion and M80 projects, this kind of infrastructure project will undoubtedly boost the local and Scottish economy, supporting hundreds of local construction and supplier jobs."
