San Antonio Freeway System
2017 Traffic Statistics

This page last updated May 10, 2018

Below are charts and maps tabulating Annual Average Daily Traffic (AADT) counts on San Antonio's freeways for 2017. The comments, rankings and calculations are the author's own analysis based on raw data from TxDOT.

The stats below are area-wide. For traffic counts only on a specific corridor, see that freeway's individual page elsewhere on this site.


Summary

Overall, traffic counts were up on average, but large sections of some freeways saw year-over-year declines including all of SH 151, the northwestern arc of Loop 410, most of US 281 North between the loops, and most of I-35. The top spot again this year was Loop 410 at Blanco with nearly 300,000 vehicles per day followed by three other locations on Loop 410 at McCullough, Vance-Jackson, and Evers, which mirrors the previous year's rankings and makes the entire segment of Loop 410 from Bandera to US 281 the busiest in the region. All but two of the remaining top 20 locations were on Loop 410 North, I-10 West, or I-35 North. The outlyers were on US 281 near the airport and I-35 just south of downtown.

Four of the top seven-- and seven of the top 12-- one-year growth locations were on I-10 East. The remainder of the top 20 one-year growth locations were scattered around the city, with six of them along Loop 1604, continuing a long trend of traffic growth on the outer loop.

The top 10-year growth spots are also widely scattered. Interestingly, the number of these locations along Loop 1604 continues to decline as it has been operating at or near capacity now for many years.


General statistics

Number in parenthesis is the San Antonio Urbanized Area's rank nationally for that category.

  • Centerline miles of freeway: 258 (21)
    • Interstate highway miles: 142
    • US and State highway freeway miles: 86
  • Percent of local roads that are freeways: 3.2%
  • Daily vehicle miles driven on freeways: 24,890,000 (21)
  • Percent of total local daily traffic carried on freeways: 50.9% (10)
