Dallas-Fort Worth Connector

The Texas Department of Transportation (TxDOT) initiated the Dallas-Fort Worth (DFW) Connector project to improve mobility along the State Highway (SH) 114/121 corridor in a safe and environmentally sensitive manner. The reconstruction and expansion project involved rebuilding the corridor through Southlake, Grapevine, and the northern edge of Dallas/Fort Worth International Airport, easing congestion in a densely populated area and substantially improving access to the airport. It is one of the largest transportation projects undertaken in North Texas (US).

DFW Connector

APPROACH

WSP | Parsons Brinckerhoff served as lead designer on the design-build comprehensive development agreement (CDA) to develop, design and build 8.4 miles (13.5 kilometres) of the DFW Connector, including major interchanges at SH 121 and International Parkway. At its widest point, the DFW Connector has 24 lanes, including 14 main lanes, 6 frontage road lanes, and 4 managed toll lanes with dynamic pricing to keep traffic moving at 50 mph (80 kph).

OUTCOME

The CDA design-build method allowed the right-of-way design and construction phases to go faster, minimizing impacts to businesses and commuters. Construction was completed six months ahead of schedule, with a savings of US$140 million.

The project received numerous awards, including:

  • PRIDE Award, from the American Road and Transportation Builders Association (ARTBA). Awarded to NorthGate Constructors for demonstrating positive community involvement and educating the public about the construction industry.
  • Globe Award, from ARTBA. Awarded for an outstanding job in protecting and/or enhancing the natural environment in the planning, design and construction of US transportation infrastructure projects.
  • Alliant Build America Award, from Associated General Contractors of America. Awarded to Northgate Constructors for Best Design-Build Highway and Transportation Project.
