Dallas/Fort Worth International Airport is 25 miles from TCU.

Love Field Airport is 35 miles from TCU. Shuttle, taxi and car rental services are available at the terminal.

Taxis, ride-share services and an airport shuttle are available at both airports.

Driving to TCU

TCU is located four miles southwest of downtown Fort Worth on University Drive. Google Maps provides the most accurate directions to campus.

From the D/FW Airport, follow the South airport exit. Take 360 South to Arlington. From 360 follow signs to I-30 West to Fort Worth. Travel through to Fort Worth (past Six Flags and the Ballpark). Travel through downtown and exit University Drive South. TCU is 2 miles from the Interstate.

From the north or south, take I-35 West to I-30 West. Travel through downtown and exit University Drive South. TCU is 2 miles from the Interstate.

From the west or east, exit I-30 to University Drive South. The campus is about 2 miles from the Interstate.

  • Continuing south on University, drive through the center of campus and turn right on W. Berry Street. (immediately after Chase Bank)
  • Continue west to the intersection of W. Berry and Wabash Ave.
  • Turn right into the parking lot entrance at Wabash Avenue. Park in any spot with white stripes.

Transportation between the hotel and TCU

Many participants are regional and have their own cars. We anticipate that informal carpooling will be enough to transport all participants to TCU and back. (The hotel is not close enough that one could walk to TCU in a reasonable amount of time.)


After 5pm on Friday you can park in any lot labeled for general faculty, staff, or student use (the lots marked CM/FS on the map and the signs). Do not park in lots labeled as reserved parking.

The CM/FS lots just south of the Sid Richardson building are probably the most convenient ones to use: - -

Lecture rooms

All talks and breaks will take place in Lecture Hall 1 of the Sid W. Richardson building. Breaks will be in Lecture Hall 3.

The physical address of the building is: 2955 South University Drive, Fort Worth, TX, 76109.

We recommend walking along either of the following paths to reach the lecture halls. There will be signs on the door of SWR; just head downstairs and you will be in front of the lecture halls:
