I-635

About I-635

Also known as LBJ Freeway, Lyndon B. Johnson Freeway.

Interstate 635 is a three-digit auxiliary route of Interstate 35, with an odd prefix digit. The number is used in two metropolitan areas. The most prominent is in Texas, where Interstate 635 forms a partial loop of about 37 miles around the north and east sides of Dallas, between Interstate 20 in Balch Springs and the north entrance of Dallas Fort Worth International Airport in Grapevine. It is signed as the Lyndon B. Johnson Freeway and is universally known as the LBJ Freeway, or just LBJ.

In Kansas and Missouri, Interstate 635 is a shorter connector in the Kansas City metropolitan area that begins at Interstate 35 in Overland Park, Kansas, and runs north across the state line and the Missouri River to a junction with Interstate 29 and U.S. 69 in Missouri. It offers an alternative to Interstate 435 for traffic seeking to bypass downtown Kansas City, and it is used heavily by north-south freight and truck traffic.

Both instances serve as connectors or partial loops around their metro areas. The Dallas route in particular has been a focus of major reconstruction, including the addition of managed toll lanes along part of its length.
