Austin County — home to the historic towns of Bellville, Sealy, and San Felipe — is one of the more rural counties in the Houston-Galveston region. Despite its smaller population, the county sees significant crash activity due to Interstate 10 traffic passing through Sealy and heavy agricultural vehicle usage on two-lane farm-to-market roads.
This analysis identifies the 10 most dangerous streets in Austin County based on total crash volume, fatalities, and serious injuries using official data from the official state transportation records.

Interstate 10: Sealy Stretch
Interstate 10 dominates Austin County's crash data with 1,075 crashes, 13 fatalities, and 50 serious injuries — accounting for 38% of all crashes in the county. The Sealy area stretch sees a dangerous mix of high-speed interstate traffic, Buc-ee's and outlet mall visitors making sudden exits, and freight trucks heading between Houston and San Antonio.
Why I-10 Is So Dangerous Here
The Sealy stretch of I-10 features the popular Buc-ee's travel center and Houston Premium Outlets, which create unusual traffic patterns as drivers decelerate suddenly from highway speeds. Combined with the high percentage of commercial truck traffic and limited lighting in rural sections, this creates conditions ripe for severe crashes.
SH 36: Bellville's Central Artery
State Highway 36 ranks second with 692 crashes, 4 fatalities, and 26 serious injuries. This highway serves as the main commercial corridor connecting Bellville to Sealy and continuing north toward Brenham, carrying both local traffic and regional through-traffic.
Rural FM Roads: Small Numbers, High Severity
FM 949 and FM 3013 each have only about 50 crashes but combine for 6 fatalities. These narrow, unlit rural roads with high speed limits and no shoulders are especially dangerous at night and during harvest season when agricultural equipment shares the road.
