SH-99 GRAND PARKWAY SEGMENTS F-1, F-2 & G

The overall Grand Parkway project, or SH-99, is the biggest single design-build contract that Texas Department of Transportation’s (TxDOT) ever awarded. The project consisted of 184-mile controlled-access tolled highway crossing seven counties in the Greater Houston area. Zachry Construction Corporation led a joint venture partnership to design and build Segments F-1, F-2 and G.

The joint venture team challenged its design and construction members to develop and design a project approach that is innovative and tailored to meet TxDOT’s needs. The result is a value-added concept that brings technical solutions and cost reduction through the implementation of alternative technical concepts (ATC).

The project’s scope of work on Segments F and G involves design, construction, utility relocations, right-of-way (ROW) acquisition and five- to 15-year capital maintenance options.

Major quantities include 38 miles of divided two-lane highway, more than 120 bridges, one river crossing (San Jacinto River), 1.8 million square yards of concrete paving, frontage roads and associated drainage, as well as several hundred existing utility relocations. In order to construct the highway, 435 parcels of land encompassing more than 2,100 acres were acquired through the ROW process. Once complete, these segments of the Grand Parkway extend from US 290 to US 59, connecting with four major interchanges: US 290, SH 249, I-45 and US 59.

The segments of SH 99 improve access to the George Bush Intercontinental Airport, the Hardy Toll Road and the new ExxonMobil campus for the hundreds of thousands of Houston-area residents who travel these routes daily — all while providing a safer experience for everyday and emergency situations.

LOOP 1604 FROM IH-10 TO US 281

The project expands Loop 1604 from a four-lane expressway to a ten-lane facility, including new eastbound and westbound mainlanes, improvements to existing pavement, and portions of the planned IH-10 direct connectors. Additional work includes reconfigured auxiliary lanes, entrance and exit ramps, and widened mainlane and frontage road bridges. A major component of the project comes…

PORT SAN ANTONIO TAXIWAY M

The Port San Antonio Consolidated Facility Package 3: Taxiway M project includes construction of new airfield pavement and supporting infrastructure at Port San Antonio. Zachry’s scope includes excavation and soil preparation, followed by lime treatment, cement-treated base, concrete paving, and asphalt paving. The project also includes site drainage, utilities, and flatwork to support the new taxiway infrastructure. The combination of pavement, utility, and drainage improvements requires careful coordination across multiple scopes to deliver a complete and durable airfield facility. Together, these improvements will provide the infrastructure needed to support continued development and operations at Port San Antonio.

US 29/US 74 BRIDGE REPLACEMENT OVER CATAWBA RIVER

The North Carolina Department of Transportation selected Zachry Construction Corporation as the prime contractor for the U.S. 29/U.S. 74 bridge replacement over the Catawba River and the associated N.C. 7/U.S. 74 improvements in Gaston and Mecklenburg counties.
