Cost: $10,000,000

Completion Date: 2015


SAI was responsible for the final alternate design of a two-span steel structure with a pedestrian walkway over the CSX Railroad in Pittsburgh, Pennsylvania.

The physical features of this project include:

  • 376′ two-span steel composite multi-girder bridge over the CSX Railroad.
  • Bridge deck consists of three 12′ lanes, two 4′ shoulders, and a 10′ pedestrian walkway that comprise approximately 20,304 sq. ft. of deck area.

Other features of this project include:

  • Structure skew is 75 degrees with substructure units consisting of integral abutments and a wall pier on a pile supported footing.
  • Investigated alternate design to develop cost-saving measures including eliminating an entire girder line from the as-designed structure and reducing overall fabricated steel weight by approximately 270,000 lbs.  Also reduced the number of bearings and evaluated the as-designed substructure for the revised loading conditions.
