    Construction period

The $850 million SH 99-Grand Parkway, Segments H, I-1 and I-2 Construction Project spans 52.8 miles around northeast Houston within Chambers, Harris, Liberty, and Montgomery counties, making up approximately 25% of a 180+ mile circumferential scenic highway.

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 design-build construction contract for Segments H, I-1 & I-2 to Grand Parkway Infrastructure, a joint venture led by global infrastructure leader Ferrovial Construction, 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, began in 2018. Pre-construction activities included final designs of the road, right-of-way acquisition with property owners, and utility relocations.

Segments H and I-1 are approximately 37.5 miles of a two-lane toll facility with intermittent four-lane sections for passing.   Segment 1-2 is made up of Segments 1-2A and I-2B.  Segment I-2A consists of tolling equipment, upgrades and other improvements for approximately 8.7 miles of an existing four-lane facility from FM 1405 to Interstate 10.  Segment I-2B is approximately 6.1 miles of a new four-lane toll facility from SH 146 in Baytown to FM 1405.

The SH 99 Grand Parkway Segments H & I Project Will improve:

  • The connectivity within the existing transportation network by providing a circumferential link between US-59/I-69 N, IH-10 € and SH 146.
  • Reduce congestion on area roadways while providing more travels options for the motorists.
  • Provide an alternate evacuation route to help relieve congestion during emergency evacuations.
  • Accommodate the forecast population growth.
  • The movement of the people and goods to businesses, places of employment, and residential areas within the region.
