Route description




State Road 510 begins at US 1, and travels northeast towards the Indian River Lagoon. It crosses the Lagoon on two bridges, with Marshall Island, providing access to an environmental learning center in between the two bridges. East of the river, SR 510 enters Wabasso Beach and heads east towards its eastern terminus of State Road A1A, one block west of the beach. The Indian River Lagoon Scenic Highway turns north on A1A until Cape Canaveral. The entire road is only 2 lanes wide, even at the causeway.
