Jefferson County Texas map
29.85° N · 94.15° W · County seat: Beaumont · 1,113 sq mi · Central Time
On 10 January 1901 a drilling crew on a low salt-dome mound south of Beaumont hit the Lucas Gusher, and the oil age in Texas started in Jefferson County. The refineries that followed are still the point of the place: the Sabine-Neches ship channel runs up the county's eastern edge past Port Arthur and Port Neches to Beaumont, and a fifth of the county's 1,113 square miles is water.
Beaumont sits at the top of the county on the Neches River; Port Arthur, Groves, Nederland and Port Neches cluster around the head of Sabine Lake to the southeast. The blank southern third is marsh and beach.
Where Jefferson County is
This is the southeastern corner of Texas above the Louisiana line. Hardin County is north across Pine Island Bayou, Orange County northeast across the Neches River, Liberty County northwest and Chambers County southwest. East, across Sabine Lake and the Sabine River, is Cameron Parish, Louisiana. The southern boundary is the Gulf of Mexico.
Both of the county's big cities have their own pages here: Beaumont is 16 miles north of the county's centre point and Port Arthur 13 miles east. Beyond the county line, Galveston is 55 miles southwest in a straight line and Houston 73 miles west. Beaumont, Port Arthur and the city of Orange next door are known collectively as the Golden Triangle, a name that came out of the oil boom and stuck to the metropolitan area.
Jefferson was one of the original counties created by the Republic of Texas in 1836 and carries the name of Thomas Jefferson. Its shape is set by water on three sides: Pine Island Bayou on the north, the Neches on the northeast, and Sabine Lake and Sabine Pass — the natural outlet to the Gulf — on the east.

Roads
- I-10 – the east–west spine, entering from Chambers County near Winnie, crossing Beaumont and leaving over the Neches toward Orange and Louisiana.
- US-69, US-96 and US-287 – the three run together as the freeway south from Beaumont through Nederland and Groves into Port Arthur; north of Beaumont they split for Woodville, Lufkin and the Piney Woods.
- US-90 – the old highway west from Beaumont through China and Nome toward Liberty, parallel to I-10.
- SH-73 – west from Port Arthur across the rice prairie to Winnie, where it meets I-10.
- SH-87 – south out of Port Arthur to Sabine Pass, then west along the beach; the coastal stretch toward High Island has been closed since Gulf storms took the roadbed out.
- SH-124 – south from High Island and the SH-73 corridor to the beach at the McFaddin refuge.
- SH-347 and SH-105 – the surface routes between Beaumont, Nederland and Sour Lake.
- SH-82 – the short leg east from Port Arthur toward the Louisiana line.
Spindletop and the refineries
The Lucas Gusher blew in on the Spindletop salt dome south of Beaumont in January 1901 and produced more oil in a day than any well drilled to that point in the United States. The boomtown that grew around it is gone, but the industry it started never left: refineries and petrochemical plants line the Neches and the ship channel from Beaumont down through Port Neches to Port Arthur, where the Motiva plant is the largest refinery in the country by capacity. Spindletop-Gladys City, a reconstructed 1901 boomtown museum, stands on the Lamar University side of Beaumont, and Lamar itself grew out of a college founded to serve those plants.
The Sabine-Neches Waterway is the reason the plants are where they are. It is dredged from the Gulf through Sabine Pass and up Sabine Lake, splitting to serve Port Arthur, Port Neches, Beaumont and Orange, and it moves more crude and refined product than most American ports.
The marsh coast
The southern third of the county is coastal prairie and salt marsh with almost nobody living in it. Sea Rim State Park sits on SH-87 southwest of Sabine Pass, with several miles of Gulf beach on one side of the road and marsh boardwalk and paddling trails on the other. West of it, the McFaddin National Wildlife Refuge covers a long stretch of the same shoreline, protecting the freshwater and brackish marsh that wintering waterfowl use. Both take the full force of hurricanes coming ashore here, which is why the beach highway between them and High Island is no longer a through route.
