There are seven bridges over the St. Johns River at Jacksonville. They include (starting from furthest downstream) the Napoleon Bonaparte Broward Bridge (Dames Point) (which carries Interstate 295 Eastern Beltway traffic), the John E. Mathews Bridge, the Isaiah D. Hart Bridge, the John T. Alsop Jr. Bridge (Main Street), the St. Elmo W. Acosta Bridge, the Fuller Warren Bridge (which carries I-95 traffic) and the Henry Holland Buckman Bridge (which carries I-295 North/South traffic). Also, next to the Acosta Bridge is a large jackknife railroad bridge built in the 1920s by Henry flagler's FEC railroad.
