Description 

Bridge with steel draw swing span completed in September or October 1912. Carried the Old Spanish Trail and US 90 until being re-routed onto what is now US 90 BUS/LA 182 in 1928. The bridge remained in use, providing access between Morgan City and Avoca Island until it was damaged in 1938. Repairs were planned but apparently not carried out. A temporary ferry service became permanent and still operates as of 2017.
