A division of the Colorado Department of Transportation is proposing toll lanes to be added to some of the state’s current interstate-style highways.

The proposal by the Statewide Tolling Enterprise is part of a plan to raise money for highway improvements, The Summit Daily News reported Jan. 29. Under the plan, drivers could choose to pay a toll to avoid congestion in non-toll lanes.

The proposal envisions toll-only lanes on a number of Colorado highways. Candidates include:

• I-70 between Denver and the Utah border
• Colorado State Highway 470 from Wadsworth to I-25;
• U.S. Highway 285 from the mountains into the Denver area;
• I-76 from Denver to the Nebraska border;
• U.S. 85 from Denver to Greeley; and
• The Boulder Turnpike.

Over the next year, Colorado DOT officials will narrow the list based on traffic, congestion, financial feasibility and other factors.
