Also known as the Isaiah David Hart Bridge and The Green Monster.

| Bridges Now and Then posted "May 3, 1967: The final support that will connect the imposing superstructures of the Hart Bridge (Jacksonville, Florida) is raised to position." (Foster Marshall/Florida Times-Union) Frank Unger: Named after Isaiah D. Hart, who founded and platted the urban core of Jacksonville in 1822. Probably the least traveled bridge, of seven (eight, if you count the Florida East Coast Railway Bridge, the oldest river crossing) in Jacksonville. A best kept secret for those that know how to get around town. Also nicknamed the “Green Monster”, as it is the dreaded uphill trek during the last leg of the annual 15K River Run; it’ll make you or break you. |
I discovered this bridge while I was looking for an overview of the Main Street Bridge.
