The Colorado Department of Transportation will begin construction to replace an emergency-access underpass near the Eisenhower/Johnson Memorial Tunnels next week, a project that is expected to run throughout the summer and fall and into next year.
In March 2020, CDOT began designs for the replacement of a structure known as “The Box,” located about 2 1/2 miles west of the tunnels, which serves as an underground access point for ambulances, law enforcement, tow companies and other emergency services. The existing roadway, a single-lane concrete box culvert, was built in the late 1960s during the original construction of Interstate 70 but is now considered “structurally deficient” and functionally obsolete, according to CDOT.
