Eisenhower Tunnel

EJT 2013

Tunnel Overview

The Eisenhower/Johnson Memorial Tunnels are in the Colorado Department of Transportation's Denver Metro region (Region 1, in Maintenance Section 9), and help move people and goods from the eastern slope of the Rocky Mountains to the western slope.

The tunnels are approximately 60 miles west of Denver on Interstate 70. The team that manages the tunnels is one of nine Maintenance and Operations sections dedicated to developing and maintaining the best possible multi-modal transportation system for Colorado that most effectively moves people, goods and information.
