Graciano Completes Restoration of the Historic Highland Park Pedestrian Tunnel
Graciano Corporation recently completed a two-year restoration of Pittsburgh’s historic Highland Park pedestrian tunnel working with the City of Pittsburgh, and with help from The Pittsburgh Parks Conservancy. The tunnel was closed because of deterioration and safety concerns. Erosion, weather and tree roots were pushing out stone blocks and the arched tunnel was in danger of collapse, according to Casimir J. Pellegrini, engineer for the City of Pittsburgh.
