The Merritt Island Causeway, which connects Cocoa, Florida, Merritt Island, Florida and Cocoa Beach, Florida, is the second route over the Indian River Lagoon and Banana River. The causeway divides Merritt Island into eastern and western sections. The western section is the location of the Hubert H. Humphrey Bridge, under which the Intracoastal Waterway passes. The eastern section is the location of the Willard Peebles bridge over the Banana River Lagoon. In the 1960s, SR A1A was routed over the eastern causeway from present day SR 520 and SR A1A, to the present day intersection of SR 520 and SR 3 on Merritt Island. The eastern section is known as the Cocoa Beach Causeway.
