General Tips

Assume you can’t cross the course: Crossing the course with a vehicle is extremely difficult, and should be
avoided. The Austin Police Department will only allow crossings at major intersections, and only when there are
no runners present.

Park strategically: If your trip starts or ends near a section of the course, sometimes the best option may be to
park on the more accessible side of the course and walk.

Use MoPac, Lamar Blvd., & I-35: These roads are unobstructed for northbound and southbound travel.

Use Ben White Bvld. (Hwy 290) and 15th St (Enfield Rd.): These roads are unobstructed for eastbound and westbound travel.

Use Google Maps & Waze: On race day, the best traffic information can be found on sites and apps like Google
Maps ( and Waze ( The Austin Marathon street closures are submitted to these
programs in advance, and they will display the closures and the associated traffic.
