Description:

Safety, Operational and Capacity Improvements to I-270:  Improving the I-270 corridor is a priority for CDOT, FHWA, and local agencies.  The I-270 corridor provides a key transportation link carrying more than 100,000 vehicles each day. It is a critical freight corridor for the region, with freight trucks making up nearly 10 percent of its daily traffic. Constructed between 1965 and 1970, I-270 no longer meets local and regional transportation demands. The interstate carries far more traffic than it was designed for, and travel delays are persistent. The pavement and bridges are stressed by the traffic loads, and emergency repairs are regularly needed. Frequent crashes, emergency repairs, and planned maintenance require frequent closures of the highway, leading to unreliable as well as slow travel times.
