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.
