Interstate 30 (
I-30) is an
Interstate Highway in the southern United States. While most interstate routes ending in zero are major cross country routes, I-30 is a comparatively short regional route serving only two states. I-30 runs from
I-20 west of
Fort Worth, Texas, northeast via
Dallas, Texas, and
Texarkana, Texas, to
I-40 in
North Little Rock, Arkansas. The route parallels
U.S. Route 67 (US 67) except for the portion west of downtown Dallas (which was once part of I-20). I-30 intersects with only two of the 10 major north–south Interstates (
I-35W,
I-35E and
I-45) and also with the major Interstate routes
I-20, and
I-40. I-30 is known as the
Tom Landry Freeway between I-35W and I-35E, within the core of the
Dallas–Fort Worth metroplex.
