While controversy heats over the proposed final link in the metrowide beltway, one of the first arcs in the loop is due for renovations.

In 1982, the Colorado Department of Transportation broke ground on C-470 and projected 50,000 daily trips on the highway through South Jeffco, Douglas County and Arapahoe County by 2003. The real number is approaching 80,000 trips and the rush-hour traffic is bumper-to-bumper through most of the highway that runs from Interstate 70 in Golden to Interstate 25 in Highlands Ranch.

CDOT is hoping to relieve some of the congestion by either widening the highway or adding new mass transit. With the help of contractors Wilson and Co., state transport officials are embarking on a two-year $5.6 million study to explore upgrading options.

The three counties touched by the highway are pitching in funds for the study and will participate in the work. The highway also runs through Golden, Lakewood and Morrison. Wilson Associate Vice President James Brady said he has spoken with planning officials from each city, but the cities will not contribute financially.

While funding is secured for the study, funding for any potential improvements remains a major question mark. Brady said one option would be for the upgrade to pay for itself through toll lanes in the center of the highway, which may or may not be limited to high-occupancy vehicles.

CDOT is seeking public input as the study begins. Officials will host meetings over the next two years with affected neighborhoods and homeowners associations. For more information, visit www.c470.info or call 303-297-2976.
