Upcoming full closures at Eisenhower Tunnel for Fire System Testing

Motorists traveling through the Eisenhower/Johnson Memorial Tunnel (EJMT) can expect overnight single-lane closures and full bore closures starting Sunday, July 12 through Thursday, July 16 as The Colorado Department of Transportation completes testing of the fixed fire suppression system. This annual testing is crucial in ensuring the system is properly working in the event a fire breaks out in the tunnel.

Please plan ahead and please note, the full bore closures on July 13 and 14 allow for the testing to take place in a more efficient manner.
