Rainbow Bridge
Historical marker location:The rapid growth of the petrochemical industry in Jefferson and Orange counties in the early 20th century led to increased population in this area. In order to serve escalating transportation needs, plans began in the 1920s for the construction of a bridge to span the Neches River.
Due to the depressed economy and differences of opinion among business leaders, the campaign to build the bridge (led by the Port Arthur "News" and American Legion Post No. 7) lasted for seven years. In 1934 Gov. Miriam A. Ferguson signed a special law to enable county bond and Federal Public Works Administration funds to pay for state highway bridge construction.
The project engineer, G. G. Wickline, used innovative techniques to design a bridge that would cross 7,742 feet of marshy terrain and river bottom. The bridge's 680-foot central span, designed to clear a Navy ship carrying a moored dirigible, was, at 176 feet, the world's highest elevated roadbed over tidal waters.
The final cost of the bridge was $2,750,000. Its dedication on September 8, 1938, drew huge crowds and was a major local event. In a 1957 contest sponsored by the North Port Arthur Lions Club, it was named "Rainbow Bridge.".
