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).

WSP 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).
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.
