In this study, the Regional Transportation District's (RTD's) light rail operations were examined for pollutant production and runoff. Conclusions from the study: Water leaving ballasted tracks carries only a small fraction of the heavy metals that are introduced into tracks from the light rail operations. Heavy metal concentrations at the most heavily traveled light rail station showed that pollutant concentrations were far below the regulatory limits., "August 2012.", "Report No. CDOT-2012-7.

In this study, the Regional Transportation District's (RTD's) light rail tracks were modeled to determine the Rational Method runoff coefficient, C, values corresponding to ballasted tracks. The runoff coefficient for ballasted tracks is significantly larger than the previously tabulated values for railroad yards. The higher runoff coefficient reflects the design of ballasted tracks to drain rainfall as quickly as possible., "August 2012.", "Report No. CDOT-2012-8.

Wildlife fencing along highways can lower wildlife-vehicle collision rates by excluding animals from the road right-of-way. Still, animals can breach fencing and end up trapped within the fencing along the highway right-of-way, exposing wildlife and motorists to the risk of collision. Wildlife escape ramps are designed to allow animals safe passage out of the right-of-way. Few recommendations exist on effective design of escape ramps and monitoring data are limited., Jeremy L.

Rich in mining history, the Mountain Mineral Belt design segment rises from the foothills. Dotted with historic towns including Idaho Springs and Georgetown, the Mountain Mineral Belt offers scenic views, lush forests, rocky hillsides, waterways, and access to local and regional destinations and recreational opportunities. The Mountain Mineral Belt design segment contains five Areas of Special Attention (ASA) including Floyd Hill, Twin Tunnels; Idaho Springs; DLD and Empire Junction; and Georgetown and Silver Plume., Description based on online resource; title from PDF caption (viewed January 2018)

Shailen Bhatt, head of the Department of Transportation and Governor Hickenlooper and other speakers share our collective aspiration to make travel in Colorado as safe as possible by reducing crashes, injuries, and Moving Colorado Towards Zero Deaths. Colorado has made tremendous progress in reducing the deaths and preventable injuries caused by traffic crashes. In the last 10 years (2002 to 2012), traffic-related fatalities in Colorado dropped 36 percent and serious injuries declined 35 percent. Towards Zero Deaths, or TZD, is not just a slogan - it is a realistic movement that recognizes the objective for every individual, every family and every community should be zero deaths on Colorado's transportation network., video file MPEG 274MB, "March 16, 2015.", Produced by Colorado Department of Transportation, Office of Transportation Safety., Online resource; title from title screen (viewed March 2025), Performers: Shailen Bhatt, John W.
