HOUSTON – One of the largest, longest-running freeway projects in Greater Houston is the Grand Parkway. It is the outer-most loop around the metro area, with construction that has been ongoing for the past two decades. The project was first conceptualized in the early 1960s. It is divided into eleven segments, the first of which opened on August 31, 1994. That first section, Segment D, extends from the Southwest Freeway to the Katy Freeway on Houston’s southwest side.

- Segment B: This 28 mile segment extends from IH-45 (Gulf Freeway) in Galveston County to to SH-35 in Alvin and SH 288 near Rosharon, in Brazoria County. This segment is environmentally approved but construction has not begun.
- Segment C: This is a 26 mile segment extends from SH 288 in Brazoria County to the Southwest Freeway in Fort Bend County. It connects with the existing Segment D. It is currently environmentally approved, but construction has not begun.
- Segment D: Completed in 1994. It is a 17.4 mile segment from the Southwest Freeway to the Katy Freeway on Metro Houston’s southwest side.
