The Twin Tunnels project will add an additional lane of highway capacity and improve roadway geometry for about 3 miles of eastbound I-70 from the East Idaho Springs Interchange (milepost 241) to the base of Floyd Hill (milepost 244) where the project ties into an existing three-lane section. The eastbound bore of the Twin Tunnels will be expanded to accommodate the widened roadway section.
