CDOT provides update on full-bore closures of Eisenhower-Johnson Memorial Tunnel planned for this summer
Full closures will only occur a few times and only between 11 p.m. and 5 a.m.
Eisenhower-Johnson Memorial Tunnel will go through important infrastructure improvements this summer.
Presley Fowler, Region One communications manager for the Colorado Department of Transportation, said these updates will cause occasional full-bore closures, but those will only occur a few times throughout the construction season. It is estimated that any lane closures will happen this summer around June or July.
Whenever overnight lane closures are needed, they will happen between 11 p.m. and 5 a.m.
For the upgrades, crews will work on various aspects of the tunnel to improve its infrastructure. This includes upgrading the drainage, plumbing and heat tape of the tunnel; improvements to the water treatment facility to modern standards; moving the fire department hose connection from the roadway to allow better access during events; repairing the tunnel liner to prevent water from infiltrating both tunnels; repairing barrier and structural elements; replacing, repairing and inspecting grout beds that support the tunnel wall panels in the Eisenhower Tunnel; and roof repairs.
