Port Orange Causeway, Road bridge in Port Orange, Florida, United States

Port Orange Causeway is a road bridge spanning the Halifax River and Intracoastal Waterway with four lanes for vehicle traffic. An adjacent park provides boat launch areas, fishing piers, and picnic facilities for those wanting to stop and spend time outdoors.

The first crossing here was built in 1906 by the Port Orange Bridge Company, owned by S. H. Gove, using sabal palm pilings and pine timbers; Gove offered to sell it to Volusia County in 1918. A 1932 hurricane damaged it beyond repair and it was torn down, leaving Port Orange without a bridge for years. A two-lane bascule bridge paid for with tolls replaced it in 1951, and after that drawbridge aged, a four-lane high bridge opened in 1990, designated the Congressman William V. Chappel Jr. Memorial Bridge.

The bridge's official name honours Congressman William V. Chappel Jr., as designated by the Florida State Legislature. Locals more often call it the Dunlawton Bridge, after the avenue it carries across the Halifax River. The 1990 structure replaced a toll-funded drawbridge, and its four lanes now carry about 29,000 vehicles a day.

The bridge offers a straightforward crossing with clear lane markings for safe driving over water. The waterside park facilities are easy to access and provide ample parking and space for recreational activities.

The current structure maintains sufficient clearance above water to allow larger boats to pass underneath without interruption. This contrasts with its predecessor, which required drawbridge operations that stopped vehicle traffic regularly.
