The Fort Bend Parkway Toll Road is the Fort Bend County (i.e.,southern) portion of a continuous toll road connecting Sienna Plantation in eastern Fort Bend County to US 90A in southwestern Harris County. It is administered by the Fort Bend County Toll Road Authority (FBCTRA). The Harris County Toll Road Authority (HCTRA) administers the Harris County (i.e., northern) segment of the road — from just south of Beltway 8 at the county line to US 90A — and uses its purple pentagonal shield labeled as Fort Bend Toll Road (the colloquial name for the entirety). It is proposed to reach a northern terminus at the southwestern corner of Interstate 610 in the future, and SH 99 at its southern terminus.
