Below are several charts and maps tabulating Annual Average Daily Traffic (AADT) counts on San Antonio's freeways.  The comments, rankings and calculations are my own analysis based on raw data from the TxDOT 2006 San Antonio District traffic count map (the latest currently available.)

To see the previous year's traffic stats, click here.

The stats below are area-wide.  To see traffic counts along a specific corridor, see that freeway's individual page.

Summary

This was a record-setting year for traffic.  For the first time since 2000, San Antonio had a location that recorded in excess of 200,000 vehicles per day (vpd).  In fact, there were three locations that exceeded that threshold, which is a record.  (The previous record was two locations in 1999.)  Also, the top location, I-10 at Callaghan, saw 216,000 vpd, which is also a new record.  (The previous record was 209,000 vpd in 1999 at Loop 410 and McCullough.)  The other spots exceeding 200,000 vpd were I-35 at Thousand Oaks (214,000) and I-10 at DeZavala (209,000).  All but two of the top 20 spots were north of downtown.

As for one year growth, the top spot this year was US 90 West just west of Loop 1604, with an increase of more than 96% over the previous year.  This is likely due to the rapid growth along Potranco Rd. and in the Castroville area that began in 2005.  The I-10 East corridor saw the most growth overall, with counts increasing by an average of 21%.  The I-35 North and US 281 North corridors also saw solid growth.

Previously, I had also reported overall growth since 1990.  This year, I've shortened that window to show the cumulative growth over the last decade.  In that category, six of the top 10 spots-- including the top five spots-- were along Loop 1604.  The top four spots were all between I-10 West and Braun Rd.  Other corridors with impressive growth since 1996 were SH 151, I-10 West, and I-37.
