One question comes up around here a lot, especially when we’re describing waterfront property  – Is it Intercoastal or Intracoastal waterway? The correct name is actually IntRAcoastal Waterway.  The Intracoastal Waterway is a network of canals, inlets, bays, and rivers that runs from Norfolk, VA down to the Florida Keys, and along the Gulf of Mexico to Brownsville, TX. The plans for the Intracoastal Waterway go back to 1808, when Treasury Secretary Albert Gallatin proposed a system of canals that would link Boston Harbor to the harbor in Brownsville. Congress rejected that plan, but over the next few decades, the Corp of Engineers began dredging a series of canals along the US Coast.

The Gulf Intracoastal Waterway is 1,100 miles from St. Marks, FL to Brownsville, TX.
