I-70 Silverthorne to Eisenhower Johnson Memorial Tunnel Resurfacing Project | Phase 2

About the Project:

Project will consist of resurfacing eastbound and westbound I-70 from mile point 211 to the Eisenhower Johnson Memorial Tunnel (MP 213.27). Additionally, crews will remove and replace over 12,000 feet of guardrails and make drainage improvements throughout the project zone (MP 207 to EJMT).


Project Benefits

Creating a smooth roadway, placing new guardrails, and improving drainage are major elements to the overall improvement of travel time reliability, safety and mobility in the I-70 Mountain corridor.
