We have so many and such a variety of waterways in Baldwin County. The canal that created “Pleasure Island” reminds me of the canal they dug to build I65 through the Delta. Who remembers it?
Everybody who lives here crosses it. Almost nobody thinks about what it is. ⚓
The Gulf Intracoastal Waterway runs 58.9 miles across Alabama, from mile 170 near Ono Island at the Florida line west to mile 111 near Petit Bois Island at the Mississippi line. It is a working commercial channel, not a scenic canal.
The route is a stitched-together thing. It uses Big Lagoon, Old River, Perdido Bay, Bay La Launch, Wolf Bay, Portage Creek, the Bon Secour River and Bon Secour Bay, plus about seven miles of dug land cuts to connect them. Those straight stretches through the pines that look unnatural are unnatural. Somebody dug them.
The Mobile Bay to Pensacola Bay section was authorized in 1930 and finished in the early to mid 1930s at nine feet deep and 100 feet wide. Wartime need got the whole waterway enlarged during the 1940s to the 12 feet by 125 feet it holds today.
Two things about the Alabama reach are worth knowing. There are no locks. The nearest are in Louisiana. And all three crossings are fixed bridges. Foley Beach Express at mile 158.7 with 73 feet of clearance, Highway 59 at Gulf Shores at mile 154.9 with 73 feet, and the Dauphin Island bridge at mile 127.8 with 83 feet, 93 in the center. Overhead cables run at 93. Bridges monitor VHF channel 13. 🚢
System wide, the GIWW moves somewhere around 110 million tons a year across roughly 285,000 vessel transits, which makes it the third busiest waterway in the country behind the Mississippi and the Ohio. Roughly 69 million tons of that is petroleum and products and about 23 million is chemicals.
Nobody publishes a figure for just the Alabama stretch, so anybody quoting you one is guessing.
What it means locally is that the same water carrying your pontoon boat on a Saturday is carrying a loaded tank barge on a Tuesday. Give the tows room, stay out of the channel when one is coming, and remember they cannot stop.
Ninety five years old and still the reason this is Pleasure Island.
