The Isaiah David Hart Bridge was completed in 1967 at a cost of $8.83 million.

The official name of the bridge is the Isaiah David Hart Bridge after the founder of Jacksonville, Isaiah Hart.

The bridge was built on a bond to be paid off with tolls until they were lifted in 1989.

[6] The stretch of highway between downtown and Beach Boulevard is known as the Commodore Point Expressway, but more commonly referred to by locals as the Hart Bridge Expressway.

The bridge's main span is uncommon for a cantilever bridge in that the truss over the main channel tapers upward and the roadway below is suspended from the truss by steel hangers.
