Melbourne Causeway, Road causeway in Brevard County, Florida, United States

The Melbourne Causeway consists of three bridges crossing the Indian River Lagoon between Melbourne and Indialantic, carrying U.S. 192. The high-rise span, officially the Ernest Kouwen-Hoven Memorial Bridge, has twin spans 2,592.5 feet long. Two low relief bridges with no appreciable change in grade complete the crossing; the easternmost is often used by local fishermen.

Ernest Kouwen-Hoven began the second bridge across the Indian River in 1919; it opened as a toll bridge in May 1921, 9,706 feet long with a 134-foot hand-operated draw. A fill causeway opened on August 1, 1939, and a low-rise swing bridge followed in 1941, opened on August 1, 1947. The twin-span high-rise was built from 1976 to 1984.

The road is known as Strawbridge Avenue through downtown Melbourne and Fifth Avenue east of the lagoon, ending at SR A1A about 2 miles past the bridge. Each July 4 the bridge closes for a fireworks show. The easternmost relief bridge is commonly used by local fishermen.

The causeway carries U.S. 192 (SR 500) across the Indian River Lagoon; its eastern end meets SR A1A about 2 miles past the bridge. West of the bridge the road becomes Strawbridge Avenue through downtown Melbourne, and east of it Fifth Avenue. The bridge closes each July 4 for a fireworks show.

The high-rise span's official name, the Ernest Kouwen-Hoven Memorial Bridge, was dedicated by the Florida Legislature on 28 May 1978, honouring the builder of the 1921 crossing. Locals never use it; it appears only in government documents. The easternmost relief bridge, by contrast, is a regular spot for local fishermen.
