County Road 2

County Road 2 is blocked off to mitigate road safety risks after Lake County Public Works, the Colorado Division of Reclamation, Mining and Safety and Newmont Mining discovered a collapsing mine tunnel under the asphalt. 

Lake County Public Works closed off County Road 2 to vehicle traffic last Thursday after discovering a decades-old collapsing mine tunnel beneath the asphalt. 

Public Works, the Colorado Division of Reclamation, Mining and Safety, Newmont Mining and a team of geotechnical engineers have been observing the subsidence, or movement of the earth’s surface, in the area over the last several years. 

Public Works decided to close off the road after the team discovered the collapsing tunnel so it doesn’t cave in and give way to a void underneath, said Lake County Public Works Director Michael Irwin. 

Vehicles and heavy equipment are banned from traveling on CR2 stretching from the bottom to top corner of Printer Boy Hill until mitigation work is completed. Recreation uses like snowmobiling, skiing and snowshoeing are still allowed, however. Yurt parking and turnaround areas are also still accessible. 

The county does not have an estimate on when remediation might begin since stakeholders are unclear who is actually responsible for performing the work on the decades-old mining tunnel, said Irwin. 

Lake County Public Works plans to update the community with any roadway status changes.
