Projects

The Eisenhower Johnson Memorial Tunnel (EJMT), about 60 miles west of Denver on Interstate 70, EJMT traverses through the Continental Divide at an average elevation of 11,112 feet. The tunnels are just over 1.5 miles long and at peak travel times carry as many as 3,500 vehicles per hour (VPH) in one direction of travel alone. I-70 is a critical corridor for moving goods and services such as medical supplies, food, and other essential items and as such, EJMT is a vital piece of infrastructure to keep I-70 traffic moving safely and efficiently. 

Opened in 1973 (Eisenhower Tunnel Bore) and 1979 (Johnson Tunnel Bore), EJMT is faced with outdated and aging infrastructure which CDOT began repairing through a variety of construction projects starting in the summer of 2022 and into the next several years. These projects are part of CDOT’s 10-Year Plan.

These projects will reduce the vulnerabilities EJMT faces and increase the resiliency and operating condition of one of the state of Colorado’s greatest assets. The improvements will enhance safety for the traveling public, upgrade connectivity to the rest of the freight network in the United States, and boost economic vitality along the only contiguous east/west interstate in Colorado.
