Around 1958, a system of freeways was built in Jacksonville. This system included an eastern approach for the recently opened Fuller Warren Bridge, along with the older Acosta Bridge and Main Street Bridge, carrying traffic to the Philips Highway (U.S. Route 1 (SR 5)) and Atlantic Boulevard (US 90 (SR 10)). A new approach to the Acosta Bridge was built, splitting from the old one two blocks north of Miami Road, and passing over the intersection of Miami Road and San Marco Boulevard before merging with the other bridge approaches. The old approach became southbound only, and northbound access was provided at Mary Street, two blocks north of Miami Road. A northbound exit was also provided at Mary Street for traffic coming from the south and east. No southbound entrance was provided, but the adjacent Main Street Bridge approach provided access in that direction.
