Northgate Constructors Team Experience

	I-10 Katy Freeway – Houston, Texas Selected by TxDOT, PB Americas Inc. is general engineering consultant for the $2.8 billion IH-10 reconstruction. The project includes rebuilding and adding seven lanes to more than 22 miles of freeway and three major interchanges. Four high occupancy/toll lanes and an integrated traffic monitoring and management system are also in the project scope. As GEC, PB operates as an extension of TxDOT overseeing the entire design phase.
	High Five Interchange – Dallas, Texas The $261 million Dallas High Five project is a five-level interchange at the intersection of US 75 Central Expressway and IH 635 LBJ Freeway. The project involved the construction of 43 bridges covering 2.3 million square feet, 630 columns and 591,000 square feet of concrete paving. The High Five project is one of the largest interchanges ever awarded by TxDOT.
	SH 45/Loop 1 Interchange – Williamson County, Texas A Zachry and Kiewit joint venture was awarded the $81 million contract to build a new interchange at SH 45 and Loop 1, the first in a series of projects on the 65-mile, $2.9 billion Central Texas Turnpike. With more than 1.5 million square feet of direct-connect bridge structures, the purpose of this project was to significantly reduce congestion in the North Austin area.
	Travis County Loop 1 – Austin, Texas A Zachry and Kiewit joint venture was awarded this project to extend the existing MoPac Expressway (Loop 1) to intersect with the future SH-45. Work on this $129 million project included construction of 3.4-mile, six-lane highway with intermittent frontage roads; a four-level intersection to connect the two roadways; three toll ramps and a toll plaza for Austin's gateway to the Central Texas Turnpike.
	IH-30 Tom Landry Freeway – Dallas, Texas Kiewit was awarded this $112 million project to widen and reconstruct a section of IH-30. The work involved almost 4.5 miles of reconstruction to create four lanes in each direction, reconstruction of 11 bridges, construction of retaining walls, and drainage enhancements. To minimize inconvenience to the public and to the nearly 150,000 daily motorists, Kiewit worked with TxDOT to re-phase the original 54-month project to a 30-month scheduled completion.
