Causeway Definition

Florida has thousands of bridges and causeways. Many people use the words interchangeably. So what is the difference between a bridge, a causeway and a causeway bridge?[1]

Bridge - a structure carrying a road, path, railroad, or canal across a river, ravine, road, railroad, or other obstacle.

Causeway - a raised road or track across low or wet ground.

Causeway Bridge - An earthen berm causeway with a bridge in the middle.

Earthen Berm Causeways

Many early Indian River Lagoon bridges used earthen berm causeways to transverse most of the distance across a waterway. Swing, draw, or high span bridges were then installed over the waterway's main channel to allow tall watercraft to pass through. This construction technique, first used in medieval times to cross flooded peat bogs, amounts to blocking the entire waterway with an earthen dam and leaving a small opening for water to flow through.

Indian River Lagoon causeways impede the flow of water bodies driven only by wind and minor tidal influence. They divide the lagoons into individual compartments, impede the exchange of water, disrupt the migration of marine life, and cause long water residence times that often hold pollutants for over 220 days. Causeway construction causes pockets of nutrient rich, decaying matter (detritus) to pile up in the corners; trapping and feeding the IRL's seasonal algae blooms.

The following tables display the estimated* distance across the waterway (Causeway Length), open waterway (Bridge Length), and a constriction ratio (Bridge/Causeway) for each Indian River lagoon causeway.

Bridge Data

Bridge Data Table displays the United States National Bridge Inventory[2] data for bridges in the six Indian River Lagoon National Estuary counties (Volusia, Brevard, Indian River, St. Lucie, Martin and Palm Beach). The data table includes information on over 1400 culvert, overpass and waterway bridges in the Indian River Lagoon watershed.

The bridge data table can be sorted by county, location, and roadway. It displays a bridge's physical data, construction detail, and inspection report. View Bridge Data Table for detailed information on Indian River Lagoon bridges.
