Notes

  • Until 1971, I-20 passed through downtown Dallas, Texas and Fort Worth, Texas along the Dallas/Fort Worth Turnpike, a route now signed as Interstate 30 (and called the Tom Landry Freeway). I-30 ended at the border of Dallas and Mesquite, Texas. When I-20 was built through Arlington and Grand Prairie, it took over the southern portions of Fort Worth's loop I-820 and Dallas' three-quarter-loop I-635.

  • In 1987, the I-20 designation was moved to a cutoff from Terrell, Texas to the southeast Dallas suburb of Balch Springs. Most of the bypassed segment of I-20 was already designated US 80, but that still left a three-mile segment of old I-20 west of Terrell with no designation. It is now (2004) signed westbound as "To US 80" and eastbound as "To I-20", and is officially designated as "Texas Spur 557". Note that the problem would have been avoided -- to the benefit of mapmakers and drivers alike -- if the Texas Department of Transportation had requested AASHTO designate the highway from Terrell to the I-30 intersection as "I-120", or perhaps "I-130".
