The 30th and Colorado Bike and Pedestrian Underpass project will provide important safety, accessibility, mobility and drainage improvements to the intersection of 30th Street and Colorado Avenue. The project area is an important piece of the 30th and Colorado travel corridor for the Boulder community and the University of Colorado at Boulder (CU). The existing intersection and at-grade crossings connect the CU main and east campuses, supports high frequency transit service and provides important commuting connections for vehicle travel.
Today, the average daily traffic through the project intersection ranges from 9,000 to almost 10,000 vehicles on Colorado and just over 21,000 vehicles on 30th Street. About 1,450 pedestrians and bicyclists (combined) pass through the 30th and Colorado intersection and more than 1,250 riders board and exit RTD and CU buses using the four stops at this intersection.
