NORTH GREECE ROAD OVER LARKIN CREEK BRIDGE
Faced with severe deterioration, pipe deformation, and section loss to both pipes, this federally funded bridge rehabilitation project involved slip-lining an existing 117”x79”, twin-corrugated, metal-pipe arch structure.

A hydraulic analysis of this structure revealed that constructing an asphalt or concrete-paved invert would increase 100-year, water surface elevations; therefore, as the bridge was within a detailed FEMA Flood Insurance Study area, the only feasible rehabilitation strategy was to slip-line the existing culverts with smooth, interior-aluminized, pipe arches.
This project was constructed in 2016 and was completed for less than the engineers estimate as well as the bid price. The project was also awarded an American Public Works Association award for small structures 2017.
