Interstate 635 (I-635) is a 37-mile-long (60 km) partial loop around Dallas, Texas, in the United States between I-20 in Balch Springs and State Highway 121 (SH 121) at the north entrance of the Dallas-Fort Worth International Airport in Grapevine. It intersects I-35E at exits 27B–C, but does not connect with I-35W. It is known locally as the Lyndon B. Johnson Freeway, or "LBJ", named after Lyndon B. Johnson, the former U.S. Senator from Texas, 37th Vice President, and the 36th President of the United States.

Because the portion of I-20 between US 67 to I-635 retains the name of Lyndon B. Johnson Freeway, together with the I-635 freeway, the two highways can be considered a partial (or 3/4) orbital road.

Route description[edit]

I-635 signage on the Dallas North Tollway frontage road. Galleria Dallas can be seen in the background.

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

History[edit]

A 1955 photo of the Interstate Highway city plans

I-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.

In January 1969, the first section to open to motorists was a 10-mile (16 km) section from US 75 to Barnes Bridge in Mesquite[clarification needed]. In February 1970, the highway from US 75 westward to I-35E northwest of Dallas opened to traffic. The I-635 designation was truncated in 1971 when I-20 was rerouted south of Dallas, taking over 13 miles (21 km) of I-635's former route.[1]

The connecting section of I-20 from the west was not completed until 1978. Initially, the section between I-35E and US 80 in southeast Dallas was concurrent with I-20. When the outlet for I-20 from southeast of Dallas to Terrell was completed, the I-635 designation was removed 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.

Later changes[edit]

The High Five construction project (so called because it is five levels and rises almost 120 feet (40 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.

Future[edit]

A $2.7 billion project was started on May 16, 2011, to widen I-635 and dig subsequent high-occupance toll (HOT) lane tunnels beneath the primary roadway from I-35E to the High Five Interchange, a length of 17 miles (27 km). Construction time was estimated in 2011 at five years.[3] 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).[citation needed]
