Beginning Monday, July 13, the Colorado Division of Reclamation, Mining and Safety will begin work to stabilize the mine shaft on East Cleveland Avenue that caused the sinkhole earlier this year. During these operations, traffic will be restricted to residents only along East Cleveland Avenue from Finch Avenue to Burlington Avenue.
The first phase of work will include drilling down to the floor of the shaft, and is estimated to last approximately two days. The drilling activity will operate weekdays between the hours of 8:00 a.m. and 5:00 p.m.
Once the drilling is complete, the contractor will continue on site for approximately 1-1/2 to 2 weeks to permanently stabilize the shaft by filling in the cavity with a grout mixture. After the stabilization work is complete, the Lafayette Public Works Department will repave the area.
