Purpose | The TxDOT Houston District is proposing improvements along SH 99 Segment E, also known as the Grand Parkway, from I-10 West to US 290 in Harris County, Texas. |
Description | The proposed project would consist of widening SH 99 from I-10 West to US 290, a distance of approximately 15 miles. Proposed improvements include the addition of two main lanes (one in each direction) within the existing median between the two northbound and two southbound main lanes, for a total of three main lanes in each direction, and necessary drainage improvements. The proposed project would involve an action in a floodplain. The existing roadway is a tolled facility and would continue to be tolled in the proposed design. The purpose of the proposed project is to manage congestion due to increased traffic based on an agreement between the State and the seven counties through which SH 99 passes. The entire project would be constructed within existing TxDOT right of way (ROW) and would not result in any residential or non-residential displacements. Any environmental documentation or studies, maps and drawings showing the project location and design, tentative construction schedules, and other information regarding the proposed project are on file and available for review by appointment Monday through Friday between the hours of 7 a.m. to 4 p.m. at the TxDOT West Harris Area Office located at 14838 Northwest Freeway, Houston, TX 77040. Please contact the TxDOT Public Engagement Coordinator, at 713-802-5199 or as shown in the notice. Project materials are also available online. |
