Interstate 635 (I-635[a]) is a 37-mile-long (60 km) partial loop around Dallas, Texas, in the United States between I-20 in Balch Springs and SH 121 at the north entrance of the DFW Airport in Grapevine. It intersects I-35E at exits 27B and 27C but does not connect with I-35W. I-635 and a part of I-20 are collectively designated as the Lyndon B. Johnson Freeway; known locally as the LBJ Freeway, or simply LBJ. The roadway is named after Lyndon B. Johnson, the former U.S. senator from Texas and the 37th vice-president and 36th president of the U.S. Where I-635 ends at I-20, I-20 continues the LBJ Freeway designation heading west. Since the portion of I-20 between Spur 408 to I-635 retains the same names as I-635, the two highways are considered three-quarters of the beltway around Dallas. Together with Spur 408, a portion of Loop 12, and a portion of I-35E, I-635 and I-20 complete the beltway.
