Interstate 635 or the Lyndon B. Johnson Freeway (abbreviated I-635 or locally, LBJ) is a partial loop around Dallas, Texas (USA) between Interstate 20 in Balch Springs, Texas and State Highway 121 at the north entrance of the Dallas-Fort Worth International Airport in Grapevine, Texas. The route is approximately 35 miles (56 km) long. It intersects Interstate 35E at Exits 27 B-C, and does not connect with Interstate 35W.



Interstate 635 was originally designated by the Texas Department of Transportation in 1959 as a loop around the eastern side of Dallas, connecting with I-35E to the northwest and southwest sides of the city. It was known locally as the Lyndon B. Johnson Freeway, or "LBJ" (named after the president). The section from Interstate 35E to U.S. Highway 75 (Central Expressway) was one of the busiest stretches of road in the Dallas-Fort Worth Metroplex, at virtually all hours of the day and night. It was a 10-mile (16 km) section and opened to motorists in January 1969, from US 75 to Barnes Bridge in Mesquite. The highway was extended westward to Interstate 35E northwest of Dallas, opening in February 1970. The designation was shortened in 1971 when Interstate 20 was rerouted south of Dallas, taking over 13 miles (21 km) of I-635's former route.[2] The connecting section of I-20 from the west was not completed until 1978, at which time the western portion of I-635 was briefly concurrent with I-20 between the southern intersection with I-35 and US 80. When the outlet for I-20 from southeast of Dallas to Terrell was completed, the I-635 designation was truncated from I-35E to its intersection with I-20 . An additional westward expansion (to the north entrance of DFW Airport) was designated in 1974 and opened in the 1980s.

The High Five construction project (so called because it is five levels and rises almost 200 feet (60 m) above the lowest level), a rebuild of the interchange of I-635 and US 75, was opened for traffic in February 2006. This interchange carries over 500,000 vehicles per day and was built as the largest interchange in the state of Texas to handle this vehicle load.

A multi-billion dollar project is being proposed to widen I-635 and dig subsequent HOT lane tunnels beneath the primary roadway from I-35E to the High Five Interchange. The project is among several billion dollar plus projects in the planning phase in and around downtown Dallas (along with the rebuild of the I-35E & I-30 "Mixmaster" and the new Trinity Parkway).

Route description

Interstate 635 begins at an intersection with Interstate 20 in southeast Dallas, and travels northward through Balch Springs into Mesquite, where intersects US Route 80 and Interstate 30. The route then turns to the northwest, continuing near the border between Dallas and Garland. 6 miles (9.7 km) later is takes a general westward turn as it intersects US Route 75 at the High Five Interchange. The route continues west, intersecting the Dallas North Tollway and its original terminus, Interstate 35E in Farmers Branch. The route then continues to the northwest, intersecting the President George Bush Turnpike in Irving before arriving at its final terminus at State Highway 121 at the north entrance to the Dallas-Fort Worth International Airport.
