► WHEN IT COMES to major transportation construction projects, how do you price safety? For the Colorado Department of Transportation, the $30 million expenditure in traveler safety was worth it during its lengthy - both in construction time and distance - Interstate-25 South Gap project.The transportation agency, its general contractor, and associated consultants worked with the Colorado State Patrol (CSP) and local emergency response agencies to combine conventional management of traffic methods with new smart work zone technology to decrease response times, reduce accidents, and ultimately promote safer travel in a long and tight construction zone.The approach was motivated by anticipation of increased traffic incidents and the deaths of two state patrol officers working the stretch.1-25 is a major national north-south transportation corridor, a lifeline between Denver and Colorado Springs, the state's two largest cities. More than 80,000 vehicles a day use the former four-lane divided expressway, one designed in the 1960s for much slower speeds than used today. |
