Texas State Highway 99
State Highway 99 (SH 99), also known as the Grand Parkway, is a partial beltway in the U.S. state of Texas. Its first section opened on August 31, 1994. If the route is completed, it will be the longest beltway in the U.S., the world's seventh-longest ring road, and the third (outer) loop of the Houston–The Woodlands–Sugar Land metropolitan area, with Interstate 610 being the first (inner) loop and Beltway 8 (Sam Houston Tollway) being the second (middle) loop. The proposed 176.6-mile (284.2 km) loop has been divided into 11 separate segments for construction and funding purposes. In May 2019, the Texas Department of Transportation gave the Grand Parkway a secondary designation as the Mayor Bob Lanier Memorial Parkway, honoring Bob Lanier, who served as the mayor of Houston from 1992 to 1998 and who had spearheaded the creation of the Grand Parkway.
A previous route designated SH 99 was established on August 18, 1924, from San Angelo to Fort Stockton. On June 25, 1929, SH 99 was extended to Alpine. On March 2, 1932, a spur to Sherwood with the designation SH 99A was added, but was maintained by the county. On July 23, 1934, this route was transferred to SH 10, and SH 99A was cancelled by then. The route is part of present-day U.S. Route 67 (US 67).
On October 29, 1960, a new route was designated for SH 99, from Denton to the Oklahoma state line as a renumbering of SH 10, to match OK 99 at the border. On April 29, 1968, this route became part of US 377.
On October 25, 1984, SH 99 was designated along a very similar route to its current one, but ending at SH 146 (then Loop 201) and Spur 330. On March 28, 2002, SH 99 was rerouted further east along a new route south to Spur 55 and along Spur 55 to Business SH 146. Spur 55 was cancelled, effective upon the completion of that section of SH 99 in 2008.
The Grand Parkway project is divided into several segments for construction and administrative purposes. The section from Interstate 69 (I-69) in Sugar Land north to the Westpark Tollway is the southern portion of Segment D and is maintained by the Fort Bend County Toll Road Authority. The remainder of Segment D, which runs from the Westpark Tollway north to I-10, along with the other completed segments as of 2022[update], are maintained by the Texas Department of Transportation.
Speed limits on the Grand Parkway are 65 to 75 mph (105 to 121 km/h).
Tolls may be paid using one of the Texas toll tag transponders (TxTag, EZ TAG, and TollTag), the Kansas Turnpike Authority's K-TAG, or the Oklahoma Turnpike Authority's Pikepass. No cash payments are accepted. As of 2020[update], a pay-by-mail option is available on segments maintained by TxDOT.
Segment A would extend from SH 146 near San Leon to I-45 in League City. As of November 2022[update], it is not considered a viable project.
