Unique Approaches to Solve Problems

CGA was named an Honor Award recipient for the 2021 Engineering Excellence Awards from the American Council of Engineering Companies of Iowa. The CGA team submitted their work on the Story City Historic Swinging Bridge Project in October 2020. The project involved numerous initiatives to mitigate future flooding events and bringing the structure up to code for safety purposes; both structurally and ergonomically.

The project included numerous initiatives to protect this historic monument, including:

  • Custom Protective Steel End Caps
  • Recessing Structural Fasteners into the Beams
  • Marine-Quality Lighting
  • Jacketed Wiring

The design was able to incorporate the preservation of:

  • Original Stone Towers
