SH 99 Grand Parkway

The vision for mobility using a “highway loop” around Houston dates back to the early 1960s.

More than 50 years later, this vision is becoming a reality with the design and construction of the remaining segments of SH 99 Grand Parkway,
Segments H, I-1 & I-2.

At 180+ miles, this circumferential scenic highway will be the longest highway loop in the United States, traversing seven counties and encircling the Greater Houston region, which is the fourth-most populous city in the United States.

In March 2017, the Texas Department of Transportation awarded the $855 million design-build construction contract for Segments H, I-1 & I-2 to Grand Parkway Infrastructure, a joint venture led by global infrastructure leader Ferrovial Agroman, along with Webber LLC and Granite Construction Inc.

Construction along the corridor, stretching from the US 59/69 interchange to the north and SH 146 in Baytown to the south, will begin in 2018. Pre-construction activities are currently underway, including final designs of the road, right-of-way acquisition with property owners, and utility relocations.

Fast Facts:

• Segments H, I-1 & I-2 represent 52.5 miles of the 180+-mile SH 99/Grand Parkway loop
• Acquisition of easements through 375 land parcels is expected to take 24 months
• 74 new bridges will be built as part of the project
• Nearly 25 million cubic feet of earth will be moved as part of the project
• The first segment – Segment D – of SH 99/Grand Parkway opened in August 1994; the most recent segment – Segment G – opened in March 2016
