The Indian River is a 121-mile (195 km) long brackish lagoon in Florida. It is part of the Indian River Lagoon system, which in turn forms part of the Atlantic Intracoastal Waterway. It was originally named Rio de Ais after the Ais Indian tribe, who lived along the east coast of Florida, but was later given its current name. The Indian River extends southward from the Ponce de Leon inlet in New Smyrna Beach in Volusia County southward and across the Haulover Canal and along the western shore of Merritt Island. The Banana River flows into the Indian River on the island's south side. The Indian River continues southward to St. Lucie Inlet. At certain seasons of the year, bridges have tended to impede the flow of gracilaria (a red algae), resulting in an odor of hydrogen sulfide in the area.

The Sebastian Inlet Bridge is a high concrete bridge. It spans the Indian River outlet which is also referred to as the Sebastian Inlet. It carries State Road A1A between Indian River County and Brevard County. The bridge was built by Cleary Brothers Construction Company, West Palm Beach, Florida, and was completed in 1964. A fishing-walking pier is constructed below the bridge and goes out the inlet along the jetty to the Atlantic. The bridge has a total length of 1,548 feet (472 m) with a main span of 180 feet (55 m). The vertical clearance is 37 feet (11 m). The Legislature of Florida dedicated the bridge to Robert W. Graves in 1965. In 2004 it was dedicated to James H. Pruitt. The bridge was deemed "structurally deficient" by the FDOT, as a result of Hurricane Dorian. Officials recommended the 55-year-old bridge be repaired within six years as of 2019.
