U.S. Highway 96 (US 96) is a north–south United States Numbered Highway that runs for about 117.11 miles (188.47 km) wholly within the state of Texas. Its number is a violation of the standard numbering convention, as even-numbered two-digit highways are east–west routes by rule. As of 2004, the highway's southern terminus (as well as those of US 287 and US 69) is in Port Arthur at an intersection with State Highway 87 (SH 87). Its northern terminus is in Tenaha at an intersection with US 59 (Future I-69)/(Future I-369) and US 84 (Future I-69).
US 96 begins at SH 87 in Port Arthur, at a southern terminus it also shares with US 69 and US 287. The three highways head in a northwest direction toward Beaumont. In Beaumont, the three highways briefly merge with Interstate 10 (I-10), but then split from that freeway continuing northwest. In Lumberton, US 96 separates from US 287 and US 69, and heads northeast. US 96 ends in Tenaha at a junction with US 59 (Future I-69)/(Future I-369) and US 84 (Future I-69).
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), which is one of the busiest sections of freeway in the United States with a vehicle count, as of 2006, of over 330,000 vehicles per day just outside the Loop.
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.
