I-70 Floyd Hill to Veterans Memorial Tunnels Construction

About the Project

In summer 2017, CDOT and the Federal Highway Administration (FHWA) began phase two of studying and planning improvements on westbound I-70 from Floyd Hill to the Veterans Memorial Tunnels. Among the improvements being considered: increasing travel-time reliability, increasing capacity on the highway, replacing a deficient bridge and improving the geometric design of the interstate.

This stretch of I-70 is one of the most congested locations on the westbound I-70 mountain corridor. High-traffic volume on I-70 west of Denver has led to ever-increasing periods of slow traffic, which, at times, approaches a gridlock situation. This area also is heavily impacted by adverse weather conditions.
