Overnight closures of the Interstate 70 Eisenhower Johnson-Memorial Tunnel are scheduled to begin Monday, August 31 and last through early October. Crews have been working through the summer on road repairs in the tunnel and are now ready to mill and pave the surface which is critically needed to improve safety. The tunnel will be open, but all traffic will travel through one tunnel bore while the other bore is closed for paving operations. Ten to fifteen minute travel delays are expected from 10 p.m. to midnight with minor delays for the rest of the nighttime hours.
The eastbound tunnel will close overnight Monday – Thursday, 10 p.m. – 6 a.m. from August 31 to September 3 and from September 8 to 18. Traffic will be detoured through the westbound tunnel. No planned closures over the Labor Day weekend, September 4 to 7.
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.
