TX 99:


The TX 99 expressway is located in the western suburbs of Houston. It travels from I-10 to US 59.

Detailed Description:

When it is completed, TX 99 will be the fourth freeway loop around Houston. Houston already has two freeway loops, the Downtown Loop and I-610, completed. A third freeway loop, Beltway 8, encircles Houston but still has some at-grade intersections in the Northeast quadrant. Very little of the fourth freeway loop is complete yet. There are two segments currently signed as TX 99. First, there is a 2-lane road east of Baytown. Second, there is a 4-lane expressway from I-10 to US 59. This expressway has different characteristics along its 14-mile journey. Some segments have a very wide median, some have a concrete barrier, and some are undivided. Some junctions have interchanges, some have traffic lights, and some have 4-way stop signs. However, the only area of the highway with driveways is the segment from Cinco Ranch Blvd to I-10, and that segment is currently under construction for an upgrade to freeway standards. For more information on future plans for the TX 99 beltway, see the Grand Parkway Associationís website. For more information on Houstonís freeway system, see Erik Slotbloomís excellent book called Houston Freeways.
