What is the SH 99 Grand Parkway Segments H, I-1, & I-2 Project?

The SH 99 Grand Parkway Segments H, I-1 & I-2 project is the continuation of the construction of a 184-mile highway loop around the Greater Houston area. The Segments H, I-1 & I-2 represent a 52.5-mile corridor spanning Chambers, Harris, Liberty and Montgomery counties northeast of Houston.

The project includes:

  • A new tolled two-lane controlled access facility, with intermittent four-lane sections for passing from US 59 North to IH 10 East

  • Four additional toll lanes from IH 10 East to FM 1405

  • Reconstruction of 74 bridges

  • Upgrades to the visual appearance of the corridor through aesthetic enhancements and landscaping improvements

The SH 99 Grand Parkway Segments H, I-1 & I-2 project is owned and managed by the Texas Department of Transportation. Construction is being performed by Grand Parkway Infrastructure.


The total project cost is approximately $1.28 billion. Design, construction and utilities represent approximately $895 million, which includes the addition of the Segment H Options; right-of-way acquisition, $354 million; and tolling facility, $32 million.

What is the project cost?


The project is being funded through a mix of toll road revenue bonds and government loans. A Transportation Infrastructure Finance and Innovation Act (TIFIA) loan from the Federal government and 2017 Toll Road Revenue Bonds issued by the Grand Parkway Transportation Corporation (GPTC) represent $1.13 billion of the total project cost. GPTC’s 2013 Bond Sale represents an additional $150 million.

Under a design/build approach, the contractor is responsible for both producing the roadway design and constructing the project. The design/build method can improve efficiencies, reduce costs and provide for a more timely project completion, so as to minimize impacts to affected property owners and the traveling public.

What is a "design/build" project?


The SH 99 Grand Parkway is owned by the Texas Department of Transportation (TxDOT). Grand Parkway Infrastructure will provide maintenance along portions of the project through a Capital Maintenance Agreement (CMA) with TxDOT.
