Also known as the Isaiah David Hart Bridge and The Green Monster.
The main span of 1,093' is the longest span in Florida. The total length is 3844'. Hart was the founder of Jacksonville. [

It has a long approach on the north side. That is because this bridge is part of the 5-mile Commodore Point Expressway that was built to connect downtown Jacksonville to its southwest neighborhood. [

"It’s also notable for how massive it is; according to the National Steel Bridge Alliance, it ranked as the 19th longest cantilever truss bridge in the world as of 1999." [Historic Bridfges calls it a continuous truss instead of a cantilever truss.] |
Having been built in the late 1960s, it uses modern truss construction techniques of welded built-up beams rather than v-lacing and lattice for built-up members.

And it uses bolts instead of rivets.
The bridge has been labeled as functionally obsolete by FDOT. [
news4jax] The lack of shoulders will cause a functionally obsolete designation.

"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. |

The Hart Bridge, also known as the John E. Mathews Bridge, is a cantilever bridge spanning the St. Johns River in Jacksonville, Florida. Opened in 1967, the bridge was named in honor of Isaiah D. Hart, the founder of Jacksonville. The Hart Bridge carries four lanes of traffic along U.S. Route 1 Alternate and State Road 228, connecting downtown Jacksonville to the city’s Southbank area and serving as a key route for both local and commuter traffic.
The bridge’s green steel truss structure makes it a recognizable part of the Jacksonville skyline. With a main span clearance of 141 feet, it allows vessels to pass beneath, supporting the city’s river-based commerce. The Hart Bridge is vital for access to TIAA Bank Field, home of the Jacksonville Jaguars, and is heavily used during sporting events and other downtown activities. Its role in easing traffic congestion and connecting neighborhoods makes it a significant piece of Jacksonville’s infrastructure and a notable landmark along the St. Johns River.
Pat Linning: I know this is clickbait but I can't pass this up.....the
Mathews Bridge and the Hart Bridge are 2 different bridges but not very far apart.
