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.
There are three major interchanges in between: the Southwest Freeway (I-69)/(US 59), the West Sam Houston Tollway (Beltway 8), and Grand Parkway (State Highway 99), along with several minor interchanges. The namesake of the tollway is Westpark Drive—an east–west major arterial running through a mostly industrial area. Like other toll roads in the Houston area, the speed limit is 65 mph (105 km/h)—even inside Beltway 8.
The Westpark Tollway is the first fully electronic toll road in the United States. There are no tollbooths or toll collectors along either section of the route. The only way to legally drive on the road is by using a transponder unit attached to a vehicle's windshield (either HCTRA's EZ TAG, NTTA's TollTag, TxTAG, PikePass from Oklahoma Turnpike Authority, or K-Tag from Kansas Turnpike Authority). These transponders communicate with overhead sensors to deduct tolls from the user's toll account.
