Balfour Beatty is set to start construction on a new privately funded junction on the M8 between Glasgow and Edinburgh.
The junction will provide access to the planned £650m Heartlands mixed-use development (pictured).
The junction will take 12 months to build and is the first privately-financed full motorway junction in Scotland.
Ecosse Regeneration is behind the Heartlands Development which comprises 610 hectares of land directly to the west of Whitburn, on the site of the former Polkemmet Colliery.
Plans for the site currently include 2,000 homes alongside leisure, education and community facilities and two 18-hole golf courses.
Work began on site in 2004 to decontaminate and remediate the land on the former mining site which is the size of 1,000 football pitches.
Balfour started the first phase of housing infrastructure earlier this year, and it is anticipated that Taylor Wimpey will be on site this autumn to start work on construction of the first 99 homes. Initial preparation work on the golf courses has also begun.
