The Westbound I-70 Twin Tunnels project widened the westbound bore of the tunnel in Idaho Springs to about 53-feet. This accommodates a third lane along westbound I-70 when the highway is eventually widened. Unlike the recent work done along eastbound I-70 to add a third highway lane from Idaho Springs to the bottom of Floyd Hill, this project only widened the tunnel to accommodate a future third lane. It did not include expanding westbound I-70 to three lanes at this time.
- Doing this project now saved an estimated $5 million to $7 million because the equipment, resources and detour needed to do the work were already in place.
- With a wider, brighter tunnel entrance, the traffic flow on westbound I-70 has improved as motorists are less likely to slow down when approaching the tunnel.
- Driver safety has also improved with the removal of rock from the walls above the tunnel portals and along the north side of the highway along the outside each portal.
- This project sets the stage for future westbound I-70 improvements which may use the extra lane for general purpose travel, peak period travel and/or transit.
