If you’re driving to St Paul, be sure to turn onto Luther Ln. There is parking on the south side of the building.
If you’re taking public transit, it is convenient to take CapMetro bus route #10. To get to St Paul from the UT campus, you can take the #10 bus from any of the UT stops up to Harris Ave and Red River. St Paul will be 500 feet (152 meters) north of the bus stop. The CapMetro web page has the timetable for the #10 route.
The CapMetro Trip Planner can assist you in finding bus information.
