I-70 Twin Tunnels Project - by Shanna Lalley

If youve driven up I-70 in the past 6 months youve probably notice the construction around the tunnels as you come into Idaho Springs. You really cant miss it if you are sitting in bumper to bumper traffic twiddling your thumbs as you move along at a painfully slow speed. The Twin Tunnels Design and Construction Project was created to improve safety and mobility in the I-70 Mountain Corridor by adding one eastbound lane from the East Idaho Springs Interchange to US 6, including expanding the eastbound tunnel. Crews will also reconstruct the eastbound bridge over Clear Creek to flatten the curve at Hidden Valley. The added infrastructure will enable managed lane operations in the future. This is the first project under construction as part of the I-70 Mountain Corridor. Here is a complete description and calendar of closures.
