The Colorado Department of Transportation (CDOT) received five awards from the 2016 Engineering News-Records Mountain States Best Project competition for various transportation projects. Mountain States Best Project awards are judged based on design and construction quality, contribution to the community and the industry, and how a project overcame unusual challenges through teamwork and collaboration.

Awards that CDOT received include:

• Best Highway/Bridge Project -- CDOT twin tunnels expansion program.

• Award of Merit Highway/Bridge -- CDOT US 6 bridges design-build.

• Award of Merit Highway/Bridge -- US 36 express lanes.

• Best Project -- SH 133 Paonia Reservoir rockfall mitigation.

CDOT's $2.73 million State Highway 133 Paonia Reservoir rockfall mitigation project was designed to reduce the risk of rockfall in an area known for daily rockfall, as well as provide measures to capture some material in the event of rockfall. The rockfall mitigation included 500 hours of rock scaling, 4,000 cubic yards of trim blasting, 11,000 linear feet of drilling and anchor installation and placement of 79,000 square feet of anchored mesh along a 1.5-mile stretch of highway.
