Overview


The DFW Connector project was the largest design-build project awarded by TxDOT at the time, and was completed nine months ahead of schedule.

NorthGate Constructors, a Zachry joint venture, completed more than $1 billion worth of improvements to the SH 114/SH 121 corridor north of Dallas/Fort Worth International Airport (DFW). The DFW Connector project consisted of 8.4 miles of roadway, including four highways, two interchanges, five overpasses, 37 bridges, new direct connect ramps and continuous frontage roads. At its widest point, the SH 114 highway is 24 lanes wide.


Major quantities include 1.6 million square feet of concrete paving, 130,000 linear feet of drainage installation, 2.9 million cubic yards of excavation, 2.1 million cubic yards of embankment and 725,000 square feet of mechanically stabilized earth (MSE) wall installation.

Zachry’s trademark innovation assisted the project from the beginning. Concrete from old lanes was recycled, which lessened the amount of trucking necessary to the project. An on-site batch plant helped to streamline the concreting process, as Zachry assisted with quality control of the concrete material.


Improved logistics and a complete re-sequencing of traffic phasing lessened the impact to the traveling public.

Thanks to managed toll lanes, continuous frontage roads and the elimination of traffic lights at the interchange, the city considerably reduced traffic congestion and air pollution from the estimated 500,000 vehicles traveling the DFW Connector roads daily.
