PRIME was responsible for this two-span bridge rehabilitation/preservation project over a heavily travelled secondary roadway in a Lancaster County tourist area. PRIME performed a cursory inspection and thorough analysis of this structure including structural load ratings. This is a 2-span rolled steel beam bridge with a length of approximately 95 feet and a width of 28 feet and was originally built in 1965. The abutments are cantilever type concrete walls with spread footings, and there is a solid concrete shaft pier with spread footing in the creek bed which is founded on rock.
Working through the Pennsylvania Department of Transportation (PennDOT) District office for reviews and approvals, PRIME developed a preservation plan that included designing a latex modified concrete overlay for the existing deck, type 2 deck repairs in conjunction with the overlay, substructure patching and waterproofing, and miscellaneous construction items. The project will incorporate two-staged construction techniques and maintain a single lane of bi-directional traffic during construction.
