Cost: $4,000,000
Completion Date: Anticipated 2023

SAI was responsible for the design of the 196’ bridge carrying Kelly Road over the Shenango River using Design-Build delivery. The project included tactical demolition and partial reconstruction of a historically eligible existing truss structure.

The physical features of this project include:

  • 196′ single span structure fully spanning the Shenango River
  • The divided bridge deck consists of two 10’ lanes, two 2′ shoulders and a 5’ sidewalk
  • The superstructure is a single span steel girder structure with multiple splices
  • Substructure consists of integral abutments on taper tube pipe friction piles
  • Structure was constructed in two phases as the bridge is the only means of access across the stream

Other features of this project include:

  • Specialized demolition to carefully remove portions of the existing historically eligible truss structure for reconstruction in an adjacent park
  • Additional demolition of a two span girder bridge with grid deck
  • Hydrology and Hydraulics analysis to consider mid-stream causeway with access bridge
  • Accounted for settlement and down-drag issues with the abutments.
  • Refined analysis for redecking, erection and deck pour conditions
  • Erection and deck pour of long span narrow steel structure utilizing lateral support
