Interstate 30 (abbreviated I-30) is an Interstate Highway in the southern United States. I-30 runs from Interstate 20 west of Fort Worth, Texas, northeast via Dallas, Texas, and Texarkana, Arkansas, to Interstate 40 in North Little Rock, Arkansas. The route parallels U.S. Route 67 except for the portion west of downtown Dallas (which was once part of Interstate 20).
Interstate 30 is the shortest two-digit Interstate ending in zero in the Interstate system. The Interstates ending in 0 are generally the longest East-West Interstates. It is also the second shortest major interstate (ending in 0 or 5), behind Interstate 45.
