Roadway Engineering

Kimley-Horn can provide roadway engineering and design to meet your needs.

Safe and efficient roads are vital in connecting people and places, spurring economic development and growth from coast to coast. And adequately maintaining your road infrastructure is essential to preserve and enhance those benefits.

Great roadway design requires a sense of balance and demands attention to things that matter: maintenance of traffic, utility relocations, environmental permits, drainage needs, and the latest regulations. It also requires careful planning for the smooth and safe flow of traffic, pedestrians, and bicyclists, and to prevent needless construction delays to ensure project completion within budget and on schedule. With so much at stake, you need a partner with a track record you can count on to cover all your bases.

Connecting the Nation

Roadway design and engineering are mainstays of Kimley-Horn’s professional practice. We have provided services for urban, rural, primary, secondary, and interstate roadways for clients ranging from municipalities and DOTs to private developers. We are well-equipped to address any task related to roadway design, including interchange and intersection geometrics, utility relocations, traffic control, ITS, signalization, signing and marking, structural/bridge design, retaining walls, and related features.

Selection and design of the appropriate interchange configuration requires careful consideration of projected traffic volumes, travel patterns, safety, costs, right-of-way, and constructability. From the initial Interchange Justification Report to the final approved construction documents, Kimley-Horn can deliver these projects from inception to completion.
Traditional roadway design focuses on access and mobility for motor vehicle traffic, largely ignoring other users. Kimley-Horn is committed to enabling safe, attractive, and comfortable access and travel for all users, including bicyclists and pedestrians of all ages and abilities.
Over three-quarters of public roads in the U.S. are two-lane, rural facilities. Whether widening to a multilane highway or addressing existing safety deficiencies on a high-risk road, we have the expertise to stretch limited agency resources to resolve your capacity and safety concerns.
As congestion gets worse, automobiles, bicyclists, and pedestrians experience longer delays and greater exposure to risk. When conventional intersection designs are insufficient to mitigate complex transportation problems, we address these challenges with innovative, alternative intersections such as continuous flow intersections, displaced left-turn intersections, and diverging diamond interchanges.

Whether you need to add a turn lane, build an interchange, realign a road, or a construct a highway, we provide designs and plans that you can count on and your contractors can understand. We work as an extension of your staff, designing roadways your way, within budget and on time. And when the inevitable surprises pop up, we bring you economical solutions, fast.
