DESCRIPTION:  The work for this requirement consists of reconstructing portions of the cave tour along the Historic Tour route within Mammoth Cave.  Existing trails will be reconstructed using concrete pavers, concrete paving or other suitable materials.  The project includes removal of dust and surface dirt from the existing trail surfaces, reconstruction of the surface (including some fill to reduce extreme grade changes), installation/replacement of steps, elevated walkways in two locations, upgrade of safety rails and installation of lint guards along most of the edges of the trails.
