Westheimer Road in the context of George Bush Park

Westchase is a business district and neighborhood in western Houston, Texas, bounded by Westheimer Road on the north, Gessner Road on the east, Houston Center Boulevard on the west, and Westpark Tollway on the south. The area is bisected by Beltway 8. Westchase is adjacent to Greater Sharpstown, the International District (which includes part of Chinatown), and the Royal Oaks Country Club subdivision. The area is immediately northeast of Alief.

A large portion of Westchase is covered by a special district, the Westchase Management District, which was created by the Texas Legislature in 1995. This entity, funded by a tax increment on businesses within its boundaries, provides branding, urban planning, and public safety functions for its constituents.

State Highway 6 (SH 6) runs from the Red River, the Texas–Oklahoma state line, to northwest of Galveston, where it is known as the Old Galveston Highway. In Sugar Land and Missouri City, it is known as Alvin-Sugarland Road and runs perpendicular to Interstate 69/U.S. Highway 59 (I-69/US 59). In the Houston area, it runs north to Farm to Market Road 1960 (FM 1960), then northwest along US 290 to Hempstead, and south to Westheimer Road and Addicks, and is known as Addicks Satsuma Road. In the Bryan–College Station area, it is known as the Earl Rudder Freeway. In Hearne, it is known as Market Street. In Calvert, it is known as Main Street. For most of its length, SH 6 is not a limited-access road. In 1997, the Texas Legislature designated SH 6 as the Texas Korean War Veterans Memorial Highway.

The Westpark Tollway, also Fort Bend Westpark Tollway, is a controlled-access toll road in Texas, serving western Houston and Harris County, and northeastern Fort Bend County. Construction on the facility began in 2001 and portions of the road were opened to traffic in May 2004. Construction of the roadway was completed in August 2005. The Westpark Tollway begins on Westpark Drive just past the South Rice Avenue intersection in the Uptown District of Houston and runs approximately 22 miles (35 km) west to Farm to Market Road 1093 just past Farm to Market Road 723 (Spring Green Boulevard) in Fulshear, Texas. It runs roughly parallel and to the south of Westheimer Road (FM 1093) in Harris County and concurrently with FM 1093 in Fort Bend County.

The Harris County Toll Road Authority (HCTRA) and the Fort Bend County Toll Road Authority (FBCTRA) operate the Westpark Tollway jointly. The 14-mile (23 km) HCTRA section is simply named Westpark Tollway; however, the 8-mile (12 km) section of the toll road operated by the FBCTRA is named Fort Bend Westpark Tollway.
