The work on the Midland Tunnels has taken a few turns this summer. First scheduled, then delayed; care has been taken to assure that the renovation work causes no structural damage to the historic tunnels.

Travelers may experience delays along CR 371 today, Tuesday, June 14, while a geotechnical/tunneling engineering team from Stantec Consulting Services performs testing of the Midland Tunnel structures. Annual testing is required to assess the structural integrity of the rock. Access through the tunnel portals will be limited while the tests are being conducted this afternoon.

Delays of up to 30 minutes are possible due to the intermittent closures of the tunnels required for the testing. The engineering evaluation should be completed by the end of the day and traffic flow along CR 371 should return to normal for Wednesday, June 15.

Chaffee County continues to work with the State of Colorado’s Historical Preservation Office, Bureau of Land Management, and engineering consultants to finalize a long-term plan for structural stabilization and reinforcement of the Midland Tunnels. The designs and engineering plans for the work are currently under review. Stabilization work is intended to secure and preserve the historic tunnel structure for the coming decades.
