To reach the Southwest Dairy Center, take I-30 east out of Dallas,Texas, or west from Texarkana, to Sulphur Springs. The city is unique in that all the major thoroughfares are State Highways. Exit the Interstate at Exit 122 and travel north on State Highway 19 to State Highway 11 (also known as Houston Street.) Turn right (east) on Houston Street. The Center is less than a quarter mile down Houston on the right. There are two fourteen-foot cows (one Holstein and one Jersey) on the street side of the building.
