Alma Lee Loy Bridge, Road bridge in Indian River County, Florida.

The Alma Lee Loy Bridge is a fixed concrete bridge carrying four motor vehicle lanes and two bicycle lanes across the Indian River, linking mainland Vero Beach with Orchid Island. It crosses the Intracoastal Waterway at Statute Mile 953, just south of flashing day beacon #145A, and has a vertical clearance of 65 feet (20 m).

Construction of the Alma Lee Loy Bridge began in 1977 and was carried out by Gulf Contracting Inc. of Florida; the crossing opened in 1979 as the 17th Street Bridge. It carries Florida Department of Transportation bridge number 880077. By 2018 inspections rated it in critical condition, and in May 2020 it was assessed as structurally deficient, with a major overhaul planned for 2024.

Locals call it the 17th Street Bridge after the road it carries, while the official name honours Alma Lee Loy. The bridge crosses the Indian River at Statute Mile 953 of the Intracoastal Waterway, just south of flashing day beacon #145A, a marker boaters use to fix their position.

Expect steady traffic flow across the bridge during the day, as it serves as a main link to the barrier islands. Ongoing construction work currently affects sections of the route, so allow extra time when crossing.
