San Antonio Freeway System
2011 Traffic Statistics

This page last updated October 11, 2012

Below are several charts and maps tabulating Annual Average Daily Traffic (AADT) counts on San Antonio's freeways for 2011.  The comments, rankings and calculations are my own analysis based on raw data from TxDOT.

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


Summary

Traffic counts in 2011 mostly increased over 2010.  I-10 at Callaghan fell from the busiest spot in 2010 to eighth this year.  The top spot was Loop 410 at Blanco with a traffic count approaching 250,000 vehicles per day; that's the highest traffic count ever in Bexar County by a substantial margin.  Three new locations topped 200,000 vehicles per day for a total of nine such locations; five of them were on I-35.

The top 20 one year growth locations were spread around the city this year, but the US 281 corridor had the highest overall one year increase.  The top spot, though, was I-10 at DeZavala, which was up by nearly 50%.  However, the 2010 count appears to have been an anomaly.

Five of the top seven growth locations since 2001 are along SH 151.  Another concentration of the top 20 ten year growth locations was along northwest Loop 1604..
