Overnight full eastbound closure at Eisenhower Tunnel for fire system testing

September 4, 2019 - Denver Metro Area, Colorado

Motorists can expect a full closure on eastbound Interstate 70 just ahead of the Eisenhower-Johnson Memorial Tunnel overnight Thursday, September 5 into Friday morning, September 6 as The Colorado Department of Transportation completes testing of the fixed fire suppression system in the tunnel. The first round of testing happened in July, and this upcoming closure is to wrap up that process. The testing is crucial in ensuring the system is properly working in the event a fire breaks out in the tunnel.

The lane closure schedule is as follows:

  • Overnight Thursday, September 5 into Friday, September 6- full closure of eastbound I-70 beginning at exit 205 (CO 9, US 6) through the EJMT from 11 p.m. to 6 a.m.
  • Traffic headed eastbound on I-70 will be detoured at exit 205 over Loveland Pass (US 6) to get back onto EB I-70.

The full closure allows for the testing to take place in a more efficient manner without stopping traffic for each test.
