HOUSTON FREIGHT
Where Houston Freight Moves: the Port, the Plants and Three Interstates
Most of Houston's heavy freight starts on the east side. Refineries and chemical plants line the Ship Channel from Pasadena to Baytown, Port Houston's Barbours Cut and Bayport terminals sit on Galveston Bay, and TGS Cedar Port in Baytown spreads over about 15,000 acres with Union Pacific, BNSF and barge service. Port Houston handled a record 4.30 million TEUs in 2025, and a large share of the region's freight begins at those terminals or in the warehouses around them.
Air freight and new plants sit to the north and west. Houston's airports, led by Bush Intercontinental, set a cargo record of 562,809 metric tons in 2025, and warehouses gather around Bush Intercontinental, I-45 and Beltway 8. Generation Park in the northeast is filling with new plants, US 290 and Highway 249 are lined with plants and distribution centers to the northwest, and the Energy Corridor follows I-10 out the west side. Clear Lake, home to Johnson Space Center, sits southeast toward the bay.
Houston sits where I-10, I-45 and I-69 meet, with Beltway 8 and the Grand Parkway circling the metro. From the port a hot shot crosses town in a couple of hours, or reaches Beaumont, Corpus Christi or San Antonio the same day. Those interchanges are also among the worst in the country for trucks: ATRI ranks I-45 at I-69 No. 4 and I-10 at I-69 No. 8, so a Katy to Baytown run is timed with that traffic in mind.
The Houston–Pasadena–The Woodlands metro has about 7.9 million people and grew by 126,720 in 2025, the largest gain of any U.S. metro. That growth pushes job sites and storefronts out to Katy, Cypress, Pearland and Sugar Land, so suburban deliveries run alongside plant work.
