Florida State Road 510

State Road 510 (actually called Indian River County Road 510 west of US 1) is a road in northern Indian River County. It provides access to farmlands south of Sebastian and the beaches of the county. The road is built over the Intracoastal Waterway so motorists don't have to go on U.S. Route 192, 25 miles (40 km) north of the Wabasso Causeway to get to areas in the extreme southeastern corner of Brevard County, Florida. The entire road is only 2 lanes wide, even at the causeway.

Starting its 8.4 miles (13.5 km) at CR 512 at Vero Lake Estates, the road begins as a north-south route for 1.2 miles (2 km) as 90th Avenue, then turns east to Wabasso as Wabasso Road. After 70th Avenue, it intersects with a major junction called Indian River County Road 615. 1 mile (1.6 km) east of this point is Indian River County Road 613, 0.5 miles (0.8 km) east of that point is Indian River County Road 605 in Wabasso. A block east of the road is U.S. Route 1. East of the road, it travels on the Indian River Lagoon Scenic Highway for the rest of the way to State Road A1A, the eastern terminus. It travels over the Indian River Lagoon with 2 bridges. The roadway ends at State Road A1A at Wabasso Beach, and the Indian River Lagoon Scenic Highway turns left on A1A until Cape Canaveral. The portion between US 1 and the eastern terminus is signed as a state road. The rest is a county road.

There's a portion in Vero Lake Estates that is unpaved. That section of Wabasso Road ends at 108th Avenue. For more information, see Wabasso Road West.
