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".
