Plenum Liner Repair

About the Project

This project will make repairs to the plenum liner (a structural liner within the tunnel walls) in both tunnel bores to mitigate water intrusion within the tunnel plenum liner during freeze/thaw cycles. 

Project Benefits

This project will improve the water infiltration the Eisenhower Tunnel experiences during the freeze/thaw cycles every year. The grout injection is meant to fill the cracks that cause water to penetrate into the plenum liner and eventually leak through the walls on the roadway.  This water freezes and causes large ice blocks on some of the wall panels in the Eisenhower Tunnel. This project will mitigate that issue. 

Work Schedule

• Daytime work
  • Monday through Friday, 7 a.m. to 5 p.m.
• Overnight Work
  • Sunday work hours are 10 p.m. to 6 a.m.
  • Monday through Thursday work hours are 9 p.m. to 6 a.m.

Traffic Impacts

• Daytime work: Motorists can anticipate single-lane closures
• Nighttime work: Motorist can expect an overnight full bore closure
• When a bore is closed, traffic along both directions of I-70 will be stopped at the tunnel entrance while one direction of travel is escorted through the open bore. Traffic stops will last 20 minutes, and delays are expected to be minimal due to the overnight working hours
