SUMMIT AND CLEAR CREEK COUNTIES — Overnight closures of the Interstate 70 Eisenhower Johnson-Memorial Tunnel are scheduled to begin Monday, August 31 and last through early October.

- Once the eastbound side is paved, the westbound tunnel will close overnight for paving September 21 to October 8. Traffic will be detoured through the eastbound tunnel.
- Arrangements have been made to ensure emergency vehicles will be able to get through quickly during the closures.
- The schedules above could change depending on the weather and other factors. It’s best that overnight travelers check cotrip.org for the latest information on road work, closures and other conditions.
