Seasonal Freight Patterns
How freight volume and rates change throughout the year on this lane.
Spring (Mar–May)
Construction season ramps up across both cities. H-E-B distribution increases for spring product launches. Military relocation freight (PCS season) begins in March.
Summer (Jun–Aug)
Peak military PCS (Permanent Change of Station) season drives household goods freight. Extreme heat (100°F+) is normal. Toyota Tundra production runs at full capacity.
Fall (Sep–Nov)
Hurricane season can affect Houston end of the lane. Pre-holiday retail through H-E-B distribution increases. Construction continues year-round in Texas's mild climate.
Winter (Dec–Feb)
Mild conditions — rarely below 40°F. Holiday retail peaks in December. January softening is mild compared to northern lanes. Year-round construction keeps flatbed demand steady.
Origin Market: San Antonio, TX
San Antonio is the seventh-largest city in the US, with an economy driven by military (Joint Base San Antonio is the largest joint base in the DoD), healthcare (Baptist Health System, Methodist Healthcare), Toyota manufacturing (Tundra pickup assembly), and a rapidly growing tech sector. H-E-B, Texas's dominant grocery chain, is headquartered here and operates one of the state's largest distribution networks.
Destination Market: Houston, TX
Houston receives San Antonio freight for local consumption, port export, and redistribution through its 6,800+ distribution centers. The Port of Houston and Houston Ship Channel provide export pathways for San Antonio manufacturing output. Houston's petrochemical complex also receives materials from San Antonio's manufacturing sector. The energy industry's headquarters cluster in Houston generates return freight to San Antonio.
Backhaul & Return Loads
Westbound Houston-to-San Antonio backhaul is readily available. Imported goods from the Port of Houston, energy sector equipment, petrochemical products, and consumer goods for San Antonio's 2.5 million metro population provide consistent loads. This lane is well-balanced — rates in both directions stay within 5–8% of each other, making it an efficient roundtrip for carriers.
San Antonio, TX to Houston, TX Freight FAQs
How does the Katy Freeway affect delivery timing?
The Katy Freeway (I-10 through western Houston) is the widest highway in the world at 26 lanes but is still notoriously congested during peak hours. Morning rush (7–9 AM) and evening rush (4–7 PM) can add 30–60 minutes to the final 30 miles into Houston. Carriers should time arrivals for midday or early morning to avoid the worst congestion. The Katy Managed Lanes (toll) offer faster through-flow at $5–$15 for trucks.
What military freight moves on this lane?
Joint Base San Antonio (JBSA) is the largest joint base in the Department of Defense, combining three major installations. Military freight includes: equipment transport between JBSA facilities and the Port of Houston for overseas deployment, household goods during PCS season (May–August), training supplies, and medical equipment from Brooke Army Medical Center. Military loads often require security clearances and specialized handling.
How does H-E-B affect freight volumes?
H-E-B is headquartered in San Antonio and is Texas's largest privately held company. Its distribution network generates thousands of daily truck movements, with significant volumes flowing between San Antonio distribution centers and Houston stores. H-E-B's private fleet handles much of this, but the company also contracts with carriers during peak demand. H-E-B is known for paying premium rates for reliable, on-time service.
Are there any toll roads on this route?
I-10 between San Antonio and Houston is toll-free for the majority of the route. However, the Katy Managed Lanes in western Houston are tolled ($5–$15 for trucks depending on congestion pricing). SH 130 (a parallel toll road east of Austin) is not on the direct route but can be useful for carriers heading to Austin first. Texas toll roads accept TxTag, TollTag, and EZ TAG.
