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.
