Ferrovial, the global infrastructure giant headquartered in Madrid, has been selected by the Texas Department of Transportation (TxDOT) to design, build, and maintain the SH 99 Grand Parkway Segment B-1 project southeast of Houston, Texas. Valued at approximately $1.47 billion, the nearly 15-mile corridor will span Brazoria and Galveston Counties and represents a defining moment in the ongoing completion of what is already the longest highway loop in the United States at 184 miles. Delivered under a design-build contract with a capital maintenance term of up to 15 years, the scope covers four new tolled lanes operated by TxDOT, discontinuous frontage roads, direct connectors at SH 35 and the new SH 99 alignment, and operational upgrades to SH 35. The project will serve the fast-growing communities of Alvin, League City, and the surrounding Gulf Coast corridor, easing chronic congestion, strengthening regional travel reliability, and critically, bolstering emergency and hurricane evacuation capacity for one of America’s most storm-exposed metropolitan regions. Final contract execution is expected this summer, with substantial completion targeted for winter 2031 to 2032.
Completing the Loop: A Corridor Decades in the Making
The Grand Parkway was first conceptualized in the early 1960s to provide a circumferential highway serving the greater Houston region’s extraordinary population growth. Six decades on, the project is entering its final phases, with Segment B-1 opening the southeast arc of the loop that will eventually stretch from Interstate 45 South in League City to State Highway 288 near Rosharon across 28 miles. Ferrovial is no stranger to this corridor. The company previously led the Grand Parkway Infrastructure joint venture alongside Webber and Granite Construction Inc., completing Segments H, I-1, and I-2 across 52.5 miles northeast of Houston under a $1.28 billion contract awarded in 2017 and opened in 2022. That earlier work, which earned recognition at the Engineering News-Record Best Projects awards, gives the company a substantial institutional advantage on the new southeastern extension. The scale of investment in SH 99 as a whole reflects a broader Texas pattern of aggressive toll road expansion to absorb surging suburban demand. A comparable programme can be found in North Texas, where the North Tarrant Express managed under a similar public-private design-build model expanded highway capacity across five interconnected corridors. As Houston’s southeast suburbs absorb continued migration from both within Texas and internationally, the completion of the Grand Parkway loop is widely seen by planners and logistics operators alike as one of the most consequential transport investments in the Sun Belt.
