I-70 Silverthorne to Eisenhower Johnson Memorial Tunnel Resurfacing Project

About the Project:

The Colorado Department of Transportation will begin work on May 2 along east and westbound Interstate 70 from Silverthorne towards the Eisenhower Johnson Memorial Tunnel. Motorists should plan for additional construction in the surrounding area. Elam Construction of Grand Junction is the contractor for this project.

Work will take place along I-70 for 5 miles from approximately Mile Point 206, by Silverthorne, to approximately MP 212, west of the Eisenhower Johnson Memorial Tunnel. Work will include a 2” hot mix asphalt overlay, installing new guardrail, repairing the end transition rails and bridge rails and culvert installation.

The HMA will add approximately 10 years of life to the highway, provide a smoother road surface and will durability by increasing the resistance of ruts and road damage. This will allow for a smoother and safer drive for motorists.

Other benefits of the project include installation of new guardrail that will be 31 inches high, designed to meet new safety standard requirements. The higher railing will help veering vehicles remain on the road more effectively, making the highway safer for the traveling public. The former standard height of guardrail was 27 inches.
