Two Points of the Golden Triangle Sit in Jefferson County
The Golden Triangle is the local name for Beaumont, Port Arthur, and Orange. Jefferson County's own directory lists Beaumont and Port Arthur. Orange sits across the county line. The City of Beaumont ties all three cities to the area's refineries and petrochemical plants.
Spindletop started the oil boom. Ports, rail lines, pipes, plants, and shops kept the three cities tied together. The name follows work and water more than county lines.
The Sabine-Neches Waterway shows that link. The U.S. Army Corps of Engineers keeps up about 80 miles of deep channel. It runs from 19 miles offshore to the Port of Beaumont and passes the working waterfronts that shaped the Golden Triangle.
