SH 99 Grand Parkway segments H and I-1 – US 59 North to I-10 East

Segments H, I-1, and the full build-out of Segment I-2 is currently under construction based on a Design Build Agreement executed with Grand Parkway Infrastructure (GPI) on June 30, 2017. Construction is anticipated to last through spring 2022.

The following exhibits provide information on Segments H, I-1, and I-2 upon completion of the ongoing Design Build project: (You may need to download Adobe Acrobat Reader to view the maps.)

Scope information

Segments H and I-1 include 37.5-miles of a controlled access toll facility from I-69/US 59 North (the Eastex Freeway) near New Caney, to US 90 near Dayton, to I-10 East (the East Freeway) near Mont Belvieu. It traverses through Montgomery, Harris, Liberty, and Chambers counties. Starting from its connection to Segment G at I-69/US 59 North, the first 8 miles of Segment H consists of four lanes, two in each direction, located within Montgomery and Harris counties. The remaining portion of Segment H and I-1 consist of two lanes with intermittent four-lane passing sections.

Segment I-2, starting from I-10 East to SH 146, is composed of Segments I-2A and I-2B. Segment I 2A, from I-10 East to FM 1405, has been open to traffic since March 2008 and includes a four-lane controlled access toll road from I-10 East to Fisher Road. Segment I-2B provides for a four-lane controlled access toll road from its connection at Segment I-2A to SH 146. It includes frontage roads on both sides of the mainlanes except at Cedar Bayou and Goose Lake where each frontage road converges to use the mainlane bridges crossing over these waterways (see Segment I-2 Maps above).
