The project scope included demolition of the two existing bridge structures, construction 18,000sf of structural earth wall, placement of 22,000cy of gravel borrow, installation of  new storm sewer, 2000cy of concrete paving, 2500sy of new sidewalk and the construction of the new bridge.  The bridge substructure consisted of one abutment wall at the south end of the bridge and four piers (built with crash walls).  The superstructure consisted of four spans (each with ten girders) of thin-flanged bulbed-tee precast girders with the longest span being just over 125 feet.  The bridge deck ranged from 8.25 inches thick to 12.5 inches thick.
