The Melbourne Causeway is located entirely within Brevard County, Florida in the United States. It is composed of three bridges and connects the municipalities of Melbourne and Indialantic across the Indian River Lagoon in Brevard County. The causeway is part of U.S. 192 (also known as SR 500), whose eastern terminus is located approximately 2miles east of the bridge, at SR A1A. East of the bridge, the road is known locally as Fifth Avenue. On the western side, the road continues through downtown Melbourne as Strawbridge Avenue. Each July 4, the bridge is closed for a fireworks show.
There are two bridges in Melbourne, the Melbourne Causeway and the Eau Gallie Causeway (SR 518) With the latter being named for the old city of Eau Gallie, which merged with Melbourne in 1969.
Ernest Kouwen-Hoven began construction of the second bridge across the Indian River in 1919. The first bridge was completed 2 years earlier near Cocoa, Florida. By May 1921 the bridge was complete and unofficially opened as a toll bridge. It was 9706abbr=offNaNabbr=off or nearly 2miles long (3 kilometers). Approximately 1/3 of the way from Melbourne there was a 134adj=midNaNadj=mid hand-operated draw. On September 18, 1921, the bridge officially opened. A Mr. J. E. Campbell was the first to drive across the bridge. During construction three sawmills were built by Ernest Kouwen-Hoven. They did not all exist at the same time. The first one was in Melbourne Village, the second was on the Nevin Property on Merritt Island, and the third was 5miles west of Grant.
The causeway between Indialantic and Melbourne was opened to traffic on August 1, 1939. The causeway consisted of fill material dredged from the bottom of the Indian River south of the causeway's location. The road surface was asphalt laid down and pressed by road rolling machines. The wooden bridge was largely replaced by the new causeway. The original bridge had a rotating span near the western end of the causeway to permit boat traffic to pass through and was operated by a person in a small shelter directly on the rotating section. In the following paragraph it appears that the author is referring to the replacement of the rotating draw span.
In 1941, construction began on the second bridge between Melbourne and Indialantic. This bridge was a low-rise swing draw bridge. On August 1, 1947, Mrs. Ernest Kouwen-Hoven cut the ribbon and the same J. E. Campbell that crossed the first bridge, was the first to cross this bridge.
The third bridge contains two twin spans that are 2592.5feet long. According to the Melbourne Centennial Book the official start of construction was February 2, 1976, and the bridge was expected to be complete by fall of 1977. It appears to have been delayed with the westbound span being constructed in 1977 and ending 2 years later. From bridge id numbers, it appears that the western relief bridges were also constructed during this time. Construction of the eastbound span did not begin until 1981 and finished in 1984.
The Ernest Kouwen-Hoven Memorial Bridge is the official name of the high-rise span, officially dedicated by the State of Florida Legislature on 28 May 1978. This name is not used locally, and only appears in official government documents.
These bridges are unremarkable, and have no appreciable change in grade. The easternmost relief bridge is commonly used by local fishermen.
At the base of the causeway on the western side is the Kiwanis Park at Geiger Point, a 7-acre community park managed by the Brevard County Parks & Recreation.
