Transportation
The main north-south highway on the island is State Road A1A which enters the island several miles north of the St. Lucie Inlet at Stuart Beach via the Ernest Lyons Bridge across the Indian River from Sewall's Point. A1A exits the island via the South Bridge in Fort Pierce. In Martin County, A1A is known as Northeast (or N.E.) Ocean Boulevard based on that county's naming system, while in St. Lucie County, A1A is known as South (or S.) Ocean Drive from the Martin County line north to the Fort Pierce Inlet, based on that county's naming system. At the Fort Pierce Inlet, A1A turns west onto Seaway Drive for the short distance to the South Bridge.
The only other road access to the island is in Martin County on State Road 732, N.E. Causeway Boulevard, which crosses the Indian River from Jensen Beach on the mainland over the Frank A. Wacha Bridge and Causeway. State Road 732 intersects with A1A at the entrance to Jensen Sea Turtle Public Beach.
The only internal public road in the Martin County portion is MacArthur Boulevard which runs south from A1A to the entrance to the Sailfish Point development about a mile north of the inlet. In the St. Lucie County portion of the island, there are many platted public subdivision streets and roads in the area that is within the Fort Pierce city limits. Practically all other roads on the island in either county are private roads controlled by homeowners' associations or condominiums.
