SHORING TOWERS KEEP BRIDGE OPEN TO TRAFFIC DURING REPAIRS

Shoring requirements for the rehabilitation of Spruce Run Bridge in Pennsylvania posed some difficult problems. Eleven badly deteriorated cross beams beneath the deck of the concrete arch bridge were to be cut in half and replaced one half at a time so that the bridge could remain open to traffic. Since the cross beams were supported only by two outside arches, shoring was needed on both sides of the cut and would be subjected to live loads for periods up to 1 1/2 years. Heavy-duty shoring towers with leg adjustment features were used to advantage on uneven terrain near the Spruce Run Bridge rehabilitation project.
