EN-25-CMGC-1-RFP - E-470 Widening Project from 104th Avenue to US-85

The section of E-470 which is the subject of the Project was originally constructed in 2002/2003 and consists of two lanes in each direction and interchanges at I-70, 56th Avenue, 64th Avenue, Pena Boulevard, 96th Avenue, and 104th Avenue. The Authority recently completed a traffic and revenue study that predicted the highway would experience level of service (“LOS”) D congestion in this area by 2029. The Authority has therefore decided to add a third lane to maintain a high level of service to E-470 customers. The Project will result in the addition of a third lane in both directions for the 6-mile section of the highway between 104th Avenue and US-85. Fourteen (14) bridges will be widened to the ultimate four (4) lane configuration including crossings at I-76/UPRR and US-85/BNSF RR. Grading and drainage for the Project will be constructed to accommodate the ultimate eight (8) lane configuration of the highway. The existing pavement will be overlaid.
