SAI was responsible for the erection of the 196’ single span steel multi-girder bridge.

The physical features of this project include:

  • 196′ single span steel multi-girder bridge
  • The bridge was constructed in multiple phases to allow for a single lane of alternating traffic during construction

Other features of this project include:

  • Utilized single tower near mid-span during girder erection due to long span
  • Utilized crane on causeway accessed via a temporary bridge structure
  • Additional cranes were placed behind abutments and girders were designed such that smaller cranes could pick end pieces until splices connected
  • Girders were lowered off tower and attached to existing pier near mid span to provide lateral support for system stability and wind
  • The pier attached provided support during deck placement until the final phase where the two adjacent phases were connected
  • Utilized crane on causeway accessed via a temporary bridge structure
