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.

On the western side, the road continues through downtown Melbourne as Strawbridge Avenue.

The first one was in Melbourne Village, the second was on the Nevin Property on Merritt Island, and the third was 5 miles (8.0 km) west of Grant.

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.

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.
