The 11-mile I-70 East project corridor extends through the eastern portion of the City and County of Denver. The purpose of the project is to implement a transportation solution that improves safety, access and mobility. The need for the project results from the following issues: increased transportation demand, limited transportation capacity, safety concerns; and transportation infrastructure deficiencies.

Central 70, between I-25 and Chambers Road, is one of Colorado's economic backbones: home to 1,200 businesses, providing the regional connection to Denver International Airport and carrying upwards of 200,000 vehicles per day. It's time to bring this aging highway into the 21st century and rejoin communities along the way. 

In February 2015, CDOT recommended developing the project through a P3. According to the I-70 East Value for Money analysis, the I-70 East project is not affordable under a design build model, but can be afforded under both the design, build, operation and maintenance (DBOM) and design, build, finance, operation and maintenance (DBFOM) models.
