Located between Houston, Texas and Lake Charles Louisiana, the tri-county region of Southeast Texas is a convenient hub for regional, national and worldwide commerce. Connected by Interstate Highway 10, as well as US Highways 69, 96, 90, 105 and 287, makes access to relative markets reliable and efficient. The Sabine Neches Waterway, Lower Neches Valley Authority, Sabine River Authority and the Gulf of Mexico provide water access to the region while the Jack Brooks Regional Airport and Amtrak, along with commercial transporters BNSF, UP and KCS provide air and rail service.
Southeast Texas includes part of the coast of the Gulf of Mexico and most of the Texas portion of the Intracoastal Waterway. The area is also crossed by numerous rivers and streams, the largest being the Sabine River and Neches Rivers. The large bodies of water in Southeast Texas are Galveston Bay and Sabine Lake, but the large reservoirs of East Texas are just to the north.
Near the coast, the land is low and extremely flat, and often marshy. The Piney Woods extend into the northern parts of Southeast Texas and Hardin County.
