It'll be smooth sailing down the M1 by mid-2020, with widening works between Mudgeeraba and Varsity Lakes set to start after the Commonwealth Games wrap up.
The state government has announced Seymour Whyte Constructions will lead the project, handing the company the $180,000,000 dollar contract on Wednesday.
It was chosen from three companies that submitted designs.
The project includes adding a third lane in each direction between Mudgeeraba and Varsity Lakes, as well as improving on- and off-ramps and building a new bridge for Stapley Drive at Exit 84.
It's hoped the widening will reduce congestion, improve freight efficiency and road safety, and provide better access to the Gold Coast CBD and surrounding areas.
The construction's set to take two years to complete and will create 300 jobs along the way.
