From the Daily Camera
A Colorado Department of Transportation project to add six-foot shoulders to Colo. 93 has provided the opportunity to build an underpass at a dangerous trail crossing south of Boulder.
Community Ditch Trail crosses Colo. 93 south of the intersection with Marshall Road. A guardrail on one side of the highway means cyclists and pedestrians have to cross at an angle. The visibility is poor, and cars are traveling at high speeds.
Despite the perceived hazard, there haven't been many accidents at the trail crossing. City officials said they have just one on record in which a dog was a hit.
That had led CDOT officials to be hesitant to approve a crossing at the location or approve closures to the highway that will be necessary to construct the underpass.
