So I called UTA's customer service department and got a calm, competent woman who guided me through how to get to work on the bus. First, pay $2.50 to take the No. 4 bus from about 2100 South and 1900 East west to the Central Pointe TRAX Station on about 200 West. (Be sure to get a transfer ticket.) Then take the train to 150 South 400 West, and it's a one-minute walk to the front door.
