Colorado Department of Transportation’s $72 million project reduced congestion and travel costs along I-70 between Empire and Idaho Springs by converting the eastbound shoulder into a tolled express lane during peak periods. Through this innovative strategy an extra travel lane can be added when needed and dynamic tolling guarantees motorists acceptable travel speeds. This tactic diverts up to 900 vehicles to reduce congestion along the 13-mile corridor and adjacent frontage roads. With this project, CDOT officials are facilitating commerce, freight movement and access to recreational activities, while helping travelers save time and money and generating revenue to help pay for the conscious investment.
