Below are charts and maps tabulating Annual Average Daily Traffic (AADT) counts on San Antonio's freeways for 2020. 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

As expected, due to the pandemic, traffic counts across the city dropped precipitously in 2020. Generally, counts were down about 10-15%. One location did show an increase: Loop 1604 north of Potranco, which inexplicably jumped about 67%.

Because nearly all locations saw a decline, I didn't rank year-over-year growth. However, I did still rank growth over the past decade. These showed some interesting clusters: the western Loop 1604 and US 90 area, SW Loop 410, NE Loop 1604, I-10 East, Loop 410 near the airport, and the eastern segment of Wurzbach Parkway.
