NorthGate Constructors

In response to the unique challenges of the DFW Connector project, two of Texas’ most respected organizations in the highway construction industry – Fort Worth-based Kiewit Texas Construction L.P. and San Antonio-based Zachry Construction Corporation – joined to form NorthGate Constructors, a Joint Venture.

With resources that included access to thousands of Texas-based employees and the nation’s largest privately owned equipment fleet, NorthGate Constructors delivered the DFW Connector project for TxDOT and the motorists of North Central Texas.
