The Bay City Walking Dredge #489 is nominated to the National Register under Criteria A and C for significance at the local and statewide levels in the areas of Transportation and Engineering. This was one of three walking dredges that were primary working machines that made the Tamiami highway construction project possible. The dredge's patented engineering played a pivotal role in the speed, safety, and financing in the struggle to build the Tamiami Trail through the Florida Everglades. The walking dredge was a unique invention, patented in 1918. The Bay City Walking Dredge #489 is the last known example of this type of equipment. The Tamiami Trail's construction had a great impact on property development in South Florida. The American Society of Mechanical Engineers on February 19, 1994, recognized the Bay City Walking Dredge #489 as a National Historic Mechanical Engineering Landmark.
