U.S. Highway 59 (US 59) in the U.S. state of Texas is named the Lloyd Bentsen Highway, after Lloyd Bentsen, former U.S. senator from Texas. In northern Houston, US 59, co-signed with Interstate 69 (I-69), is the Eastex Freeway (from Downtown Houston to the Liberty County/Montgomery County line). To the south, which is also co-signed with I-69, it is the Southwest Freeway (from Rosenberg to Downtown Houston). The stretch of the Southwest Freeway just west of The Loop was formerly one of the busiest freeways in North America, with a peak AADT of 371,000 in 1998.^[2]

US 59 (overlapped by US 71) actually straddles the border between Texas and Arkansas north of I-30 near Texarkana, with the east side of the highway on the Arkansas side and the west side of the highway on the Texas side. In the past, both highways remained on the border past I-30 as State Line Avenue to downtown Texarkana; today, only US 71 does so. Nearly 90 percent of this route is designated to become part of I-69 in the future. Currently 75-mile-per-hour (121 km/h) speed limits are allowed on US 59 in Duval County and portions of northern Polk County.

The total length of the southernmost segment of US 59 that passes through Texas and terminates at the Mexico–US border is 615 miles (990 km).
