Roads and highways solutions must be designed to be long-term, sustainable and cost effective, from local access roads to major urban and rural strategic routes. Improving safety, easing congestion and extending the usable life of streets and highways are always priorities.

The design of highways and streets requires a delicate balance between the physical demands of a project, the realities of constraints faced by owners and operators, and the need for design to recognize the setting of the asset in the environment. From feasibility studies to planning, design, procurement, construction supervision and post-construction assessments, engineering expertise is required to ensure optimal efficiency and safety, while minimizing costs and environmental impacts. WSP experts work on bringing these benefits to towns and cities every day.

WSP has designed highway, road and street projects around the world. Our civil engineering teams apply innovative designs to the delivery of long-term sustainable solutions for construction of new roads and streets in urban and rural environments, as well as the widening and improvement of existing roads and highways. The scope of our expertise extends to conceptual studies, preliminary engineering and detailed design of rural and urban highways, arterial roads and neighborhood streets.

In Texas, WSP served as lead designer on the award-winning Dallas-Fort Worth Connector. The comprehensive design-build project involved a development agreement to develop, design and build 13.5 km 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 fluidly.
