NASA Causeway Indian River

NASA Causeway Indian River
Three mile long NASA Causeway connects SR405 in Titusville with Kennedy Space Center's NASA Parkway in Merritt Island, Florida. The causeway's 2,990ft bridge across the Indian River spans the Intracoastal Waterway (ICW) channel with a 142ft divided, four-lane, double-leaf bascule drawbridge.
Waterway: North Indian River Road: SR405
City: Titusville County: Brevard
Type: Bascule Drawbridge Builder:McCormick and Sons
DOT: 703001 L: 2993' Built: 1964
Location: 28.5284,-80.76561


1964 NASA Parkway Causeway

SR405 NASA Causeway 1964

Built in 1964, the NASA Causeway Bridge across the Indian River has

  • reinforced concrete approaches
  • aluminum handrails
  • double-leaf bascule span
  • and an estimated 12,940 feet of earthen berm causeway.

NASA Causeway's concrete bridge approaches are 1,460 x 28 feet long and the draw span is 142.75 x 28 feet.

The drawbridge provides an estimated 105ft of clearance to vessels in the ICW Channel when the span is opened.

The bridge has a three-story concrete control house that is 14.33 x 12.75 feet. The control house is capped by a metal and glass control room with a flat roof and walls that flare out from bottom to top.

Flow Factor

SR405 NASA Causeway 2021

Our "Flow Factor" variable is an unscientific estimate of water flow constriction using Google Map Measurements.

Bridge Length / Lagoon Width = Flow Factor

2,900ft Bridge Length / 15,840ft Lagoon Width = 18.3% Flow Factor

18.3% of the lagoon's width is spanned by the bridge and not impeded by the earthen berm causeway.

NASA Causeway impedes the Indian River's water flow for an estimated 12,940ft (2.45 miles) or 81.7% of the lagoon's three mile width.
