Eastbound Twin Tunnels traffic switches to final alignment

After just eight months of rock blasting, rock bolting and paving, the third lane of eastbound I-70 between east of Idaho Springs to U.S. 6, including through the Twin Tunnels, will open to traffic next week after a 36-hour traffic switch, weather permitting.

All lanes of eastbound I-70 through the Twin Tunnels will be placed in final alignment this week, the week of Dec. 9, weather permitting. The traffic realignment was scheduled to begin 5 a.m. on Tuesday, Dec. 10, and will continue until midnight on Thursday, Dec. 12, during which eastbound I-70 will be reduced to one lane. All three lanes of eastbound I-70 through the tunnel will open by midnight on Dec.12. For updates on this project, visit

By widening eastbound I-70 through the Twin Tunnels, CDOT will be able to build an Express Lane for eastbound peak periods that uses the shoulder lane. Using the existing wide shoulder from Empire Junction through Idaho Springs, motorists will be able to travel the peak period shoulder lane by paying a toll only during peak travel times. In return, they will have a reliable travel option with consistent speeds that will save motorists an average of 30 minutes in travel time.

The peak period shoulder lane will be constructed and open to traffic in summer 2015.
