I-70 Westbound Twin Tunnels (Veterans Memorial Tunnels)
In march of this year the Colorado State Legislature proposed a bill to rename the I-70 Twin Tunnels to Veterans Memorial Tunnels. This bill was passed in April and as of the conclusion of this project, the Twin Tunnels will officially switch names. Until that time, CDOT will continue to use both Twin Tunnels and Veterans Memorial Tunnels when discussing this project so as not to create confusion.

The Westbound I-70 Twin Tunnels project will widen the westbound bore of the tunnel in Idaho Springs to about 53-feet. This will accommodate 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 will only widen the tunnel to accommodate a future third lane. It does not include expanding westbound I-70 to three lanes at this time.
There will be no lane closures on Friday, April 4, Saturday, April 5 or Sunday, April 6 for the I-70 Twin Tunnels project.
Construction updates can be found in the Travel Alerts or Road Work Alerts at www.cotrip.org so you can plan your trips accordingly in this area, delays are expected!
Blasting work inside the tunnel and on the rock face wall above the west end of the tunnel is complete. Blasting work on the rock face wall above the east side of the tunnel, however, is expected to continue through September so motorists should still plan for delays.
Tunnel widening work is on schedule for completion by the end of this year. Work will continue in 2015 to restore County Road 314, build retaining walls and make trailhead enhancements. This work is scheduled to be done in the summer of 2015.
