The Texas Department of Transportation (TxDOT) announced a plan to widen a 6.73‑mile stretch of the Grand Parkway (State Highway 99) that runs through the Spring area of Harris and Montgomery counties. The $209 million project would be paid for primarily with toll revenue, with the possibility of additional federal funding, and is intended to keep traffic flowing at a minimum‑delay level designated as a “C” on TxDOT’s grading scale.
Project details
Currently the corridor features two 12‑foot main lanes in each direction, a depressed grassy median, and two‑lane frontage roads. The proposed design would add a third 12‑foot main lane in each direction, replace the grassy median with 10‑foot paved shoulders on both sides, and install concrete traffic barriers. Right‑of‑way would remain at the existing 400‑420 feet, so no additional land acquisition is required.
Direct connectors are also part of the plan, linking southbound I‑45 to eastbound Grand Parkway and westbound Grand Parkway to northbound I‑45. These connectors would include a 14‑foot lane with 8‑foot outside and 4‑foot inside shoulders, again without needing extra right‑of‑way.
Environmental and community considerations
TxDOT indicated that the project will not add new storm‑water detention ponds or noise barriers. Existing drainage infrastructure—storm sewers, ditches, and current detention ponds—will be reviewed and modest modifications made as needed to handle the increased capacity.
The agency will conduct an environmental impact analysis, and the project could receive supplemental federal funds after that review.
Public input and timeline
TxDOT is collecting written comments through Oct. 9 via mail, email, or in‑person drop‑off. A virtual public meeting was held on Sept. 22, followed by an in‑person open house on Sept. 24. Details on how to submit feedback are available on the TxDOT website.
The projected schedule is as follows:
- 2025 – Data collection and needs evaluation
- 2026 – Environmental studies begin; mid‑year public meetings
- Early 2027 – Environmental decisions and detailed design
- Late 2027 – Construction start, with an estimated five‑year build period
This expansion aims to preserve stable traffic flow and vehicle speeds on a key regional artery that serves commuters and freight traffic throughout the Greater Houston area.
