San Antonio Freeway System
2019 Traffic Statistics

This page last updated October 10, 2020

Below are charts and maps tabulating Annual Average Daily Traffic (AADT) counts on San Antonio's freeways for 2019. 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

After just barely missing it last year, San Antonio joined the rather exclusive club of cities with a freeway having a traffic count exceeding 300,000 vehicles per day this year. The area's busiest location-- Loop 410 at Blanco-- broke into the club with a count of 305,764, up about 2% over the previous year. The two adjacent locations on Loop 410 (at McCullough and at Vance-Jackson) continue to be the second and third busiest spots in the city, followed by I-10 at Callaghan and I-35 south of Thousand Oaks. Seven of the top 10 busiest locations were along Loop 410 North, which continues to make it the busiest stretch of freeway in the region and one of the five busiest in the state. Of the top 20 locations, 19 were on just three freeways: Loop 410 North, I-35 North, and I-10 West; the lone exception was on US 281 near Nakoma. Fourteen locations now exceed 200,000 vehicles per day, up one from last year.

Overall, traffic counts were a mixed bag of increases and declines. Interestingly, large segments of Loop 1604 North and I-10 West saw declines last year. Loop 1604 on the northwest side was an exception, with the section south of Bandera Rd. crossing the 100,000 milestone, the last stretch between SH 151 and I-35 North to do so. Four of the five top locations for one-year growth were on Wurzbach Parkway; the exception was on Loop 1604 just north of US 90, which had construction completed during mid 2019.

The top 20 locations for growth over the decade are widely scattered, but form a few clusters: around the US 90 West/Loop 1604 interchange, around the SH 151/Loop 1604 interchange, on Loop 410 near the airport, along Loop 410 South, near I-10 and Loop 1604 East, and along the eastern half of Wurzbach Parkway, with a couple of outliers.
