Dallas-Fort Worth Connector

The Texas Department of Transportation (TxDOT) initiated the Dallas-Fort Worth Connector (DFW) project to improve mobility along the State Highway (SH) 114/121 corridor in a safe and environmentally sensitive manner. The reconstruction and expansion project involves 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.


WSP USA, formerly 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 kilometers) of the DFW Connector, including major interchanges at SH 121 and International Parkway. At its widest point the Connector has 24 lanes, including 14 main lanes, six frontage road lanes, and four managed toll lanes with dynamic pricing to keep traffic moving at 50 mph (80 kph).

The CDA design-build method allowed the right-of-way, design, and construction phases to be accelerated, minimizing impacts to businesses and the traveling public. Construction on the 8.4 miles (13.5 kilometers) was completed six months ahead of schedule, with a savings of $140 million. The project received the 2014 “P3 of the Year” award at the annual Public Private Partnership Conference of the American Road & Transportation Builders Association (ARTBA).
