The project proposes to replace SO-year old aging timber sets lagging underground along the Black Diamond Mine tour route on Level B. The approx. 180-foot span of existing wood Is deteriorating and visibly defective in places. New timbering will be designed and constructed to last longer while maintaining the history.
The project would replace existing and damaged timber structures and sets to meet current standards of public health and safety. Replacement Is located on the same site and will have the same purpose and capacity.
