Interstate 635 (I-635

I-635 begins at an intersection with I-20 in southeast Dallas and travels northward through Balch Springs into Mesquite, where it intersects US 80 at exits 6A and 6B and I-30 at exits 8A and 8B. The route then turns to the northwest, continuing near the border between Dallas and Garland. Six miles (9.7 km) later, it takes a general westward turn as it intersects US 75 at exits 19A and 19B 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 at exits 22B and 22C and its original terminus, I-35E in Farmers Branch at exits 27B and 27C. The freeway then continues to the northwest, intersecting the President George Bush Turnpike at exit 30 westbound and exit 29B eastbound in Irving before arriving at its final terminus at SH 121 at the north entrance to the DFW Airport.

History

I-635 was originally designated by the Texas Department of Transportation (TxDOT) in 1959 as a loop around the east 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 (now SH 310) near Hutchins to Barnes Bridge in Mesquite. In February 1970, the highway from US 75 westward to I-35E northwest of Dallas opened to traffic. The I-635 designation was truncated on December 2, 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.

On April 1, 1968,

The High Five construction project (so called because it is five levels and rises almost 120 feet [37 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.

Express project

A $2.7-billion (equivalent to $3.61 billion in 2023^[5]) project was started on May 16, 2011, to widen I-635 and dig subsequent high-occupancy toll lane tunnels beneath the primary roadway from I-35E to the High Five Interchange, a length of eight miles (13 km). Construction time was estimated in 2011 at five years and was completed and opened for traffic on September 10, 2015.^[6][7] The new highway features tolled express lanes, known as TEXpress lanes, in between the mainlanes or underneath them. The cost to drive on them fluctuates based on the current flow of traffic at the time. 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".^[8]
