You have two options. The first is Beltway 8 and from 59 back around to 59 you will have to pay a $1.25 toll two times. The second is loop 610 it is closer to town and often has a lot of traffic and construction. Personally I would pay the $2.50 if you will be coming thru during rush hour, otherwise don't take a loop at all. Hope this helps.
