Van Horn to San Antonio US 90 begins in
Van Horn at an intersection with
Bus. I-10 and
SH 54. US 90 travels in a southeastern direction towards
Marfa where it starts an overlap with
US 67. US 90 travels south and runs parallel to the
US-Mexico Border near the
Rio Grande. US 90 crosses the
Amistad Reservoir then runs through
Del Rio. US 90 turns right and runs east towards
Brackettville. US 90 runs through
Uvalde and
Medina counties. US 90 then arrives in
San Antonio where it serves as a major freeway. Multiple stack interchanges are under construction to gain access in and out of the freeway along the intersections at Loop 1604 and I-410. Further, the highway has a major junction with TX-151 as it continues eastward towards the city's inner Westside until its interchange with
I-10 and
I-35 at the southwest corner of
Downtown. File:US 90 Van Horn.jpg|South of

Del Rio San Antonio to Houston East of Downtown San Antonio, US 90
multiplexes with I-10. This overlap ends in
Seguin, and continues where the two highways continually cross each other en route to
Houston. US 90 once again
duplexes with I-10 east of
Columbus briefly separating near
Brookshire and continue overlapping from
Katy all the way to Houston. At
I-610 east of Houston, US 90 becomes independently known as the Crosby Freeway. The Crosby Freeway from east of Beltway 8 to east of Runneburg Road in
Crosby, was constructed in the early 1990s and opened to traffic in 1992. After several delays, construction work on the inner section of the freeway began in 2006 and was opened to traffic in January 2011. The western terminus of the Crosby Freeway connects to the I-610 and I-10 interchange via two freeway ramps: • a ramp from westbound Crosby Freeway, joining an exit ramp from westbound I-10 to enter southbound I-610 • a newly constructed two-lane exit ramp from eastbound I-10 connecting to eastbound Crosby Freeway. The previous interchange was a four-level
stack interchange though the new interchange is not a full five-level stack. Because of funding constraints, two sections of the freeway inside Beltway 8 were not built to full freeway standards: a half-mile section over Greens Bayou and an approximately mile-long section east of Normandy Street. As of December 2012, only the
feeder roads have been constructed, with space reserved in the median for future freeway mainlanes. Unlike most new freeway extensions in the Houston area built in recent decades, the Crosby Freeway is not tolled. Also unlike most of Houston's existing freeways and tollways, the Crosby Freeway does not have continuous
feeder roads. The Crosby Freeway has four to six mainlanes for its entire length.
Houston to Louisiana US 90 (known as the
Crosby Freeway) heads northeast leaving Houston and ends its freeway status in
Crosby. US 90 then continues traveling east through
Beaumont and is locally known as College Street, passes by Baptist Hospital Beaumont and meets I-10 at a T-interchange. It then passes through
Orange and has a business route (Business US 90-Y). It then crosses the
Sabine River into
Louisiana towards
Lake Charles. With the exception of an section with only two (briefly three) lanes between
Liberty and
Devers, US 90 has at least four lanes between
Crosby and the Louisiana state line. ==Major intersections==
