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. The route is approximately 35 mi (56.5 km) long. It intersects Interstate 35E at Exits 27 B-C, and does not connect with Interstate 35W.

Interstate 635 was shortened in 1971 when Interstate 20 was rerouted south of Dallas, taking over 13 miles of I-635's former route.^[2]

It is known locally as the Lyndon B. Johnson Freeway, or "LBJ" (named after the president) and the section from Interstate 35E to U.S. Route 75 (Central Expressway) is one of the busiest stretches of road in the Dallas-Fort Worth Metroplex, at virtually all hours of the day and night.

The High Five construction project (so called because it is five levels and rises almost 200 feet (61 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 IH-635 and dig subsequent HOV lane tunnels beneath the primary roadway from I-35E to the High Five Interchange. Dallas residents would most likely welcome this improvement to the roadway as one of a few 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).
