  • Removal of an existing single span reinforced concrete frame bridge with a sidewalk on one side.
  • Replacement was a new single span pre-stressed concrete spread box beam bridge with a sidewalk on one side.
  • The concrete spread box beam was 57’-8” (out/out) and maintained three (3) 11-0’ travel lanes, two 8’-0” shoulders, and a 5’-8” sidewalk on one side.
  • Other design build activities that SAI completed included approach roadway work, drainage, guide rail, utility relocation, and permits.
