The Stone Bridge spans the Conemaugh River in Johnstown, Pennsylvania. The bridge is a seven-arch stone railroad bridge located on the Norfolk Southern Railway mainline, built by the Pennsylvania Railroad in 1887-88. Its upstream face was reinforced with concrete in 1929. This bridge survived the Johnstown Flood of 1889, but the bridge blocked debris, which subsequently caught fire and created an inferno covering 30 acres (120,000 m2). The bridge is visible from Point Park in downtown Johnstown.
Stone Bridge project
The Stone Bridge, located on the edge of Johnstown’s downtown, is an arched bridge built by the Pennsylvania Railroad in 1887. On May 31, 1889, its seven arches blocked tons of debris, including miles of barbed wire twisted through it from the destruction of a plant; all were carried by the waters of the Johnstown Flood, but the bridge withstood its force. An enormous fire broke out in the debris at the bridge, killing scores of people trapped within it, and burning for three days.
A Johnstown landmark, the three-track bridge is still used by the railroad. Now owned by the Norfolk Southern Railway, the bridge is located near Route 56, the most heavily traveled road in the region. It is highly visible from Route 56, downtown, the Johnstown Area Heritage Association's (JAHA) newly established Festival Park, and the restaurant and visitors center above the city at the Inclined Plane. The bridge needed restoration, as its stone façade had long since been covered with concrete, added when the bridge was expanded with a third track, and its general appearance was poor.
A bridge restoration project was developed by community leaders, to include cleaning and physical and aesthetic improvements, resurfacing of the south side, and new lighting with energy-efficient LED lighting adjustable to different colors and intensities. Estimated to cost $1.2 million, the project was initiated in 2008 as part of flood commemorative activities.
Michael Brosig, co-chair of the Stone Bridge Committee, said,
"The significance of the Stone Bridge is that it stood its ground against the flood waters and altered the future of Johnstown completely and forever. It created the backdrop for the event that put Johnstown on the map. Restoring the South facade of that structure and casting LED lighting on it will certainly showcase the triumph of the human spirit in a spectacular style for all to see, enjoy and be proud of their heritage. Based on its strategic location, it is the lynchpin of the historic district of our city."
Consultants on the bridge restoration project included Shadowstone, Inc., of Clifton, New Jersey, for the lighting. For the bridge restoration and rehabilitation, the group worked with Pawlowski & Haman Architects, P.C., and H. F. Lenz Co., both of Johnstown.
