The engineering behind roadway and intersection design are changing, and we can help you stay ahead of the curve.
Surface transportation
Designing for the correct context of your roadway project is critical to a successful outcome. Our roadway specialists understand how to design for different types of roadway projects — urban, rural, low-speed and high-speed, to name a few — and we closely monitor emerging research and new context classifications. By staying at the forefront of design guideline changes, we can provide you with a design that moves you toward your goals.

Emerging technology
To help you benefit from emerging technologies, we constantly educate ourselves on developing trends, such as connected and automated vehicles, and larger, heavier vehicles, as well as how they will affect roadway design. Our experts contribute to the industry through participation on several National Cooperative Highway Research Program panels. Our knowledge and awareness of emerging technologies and the importance of all road users merge with our traditional design know-how to make your vision a reality.
Our goal is to help you provide a roadway that enhances your community’s livability and meets the needs of motorists, vulnerable road users, cyclists and pedestrians, along with public right of way and accessibility guidelines.
Focus on sustainability
We recognize that project sustainability is a key priority for your projects. We helped write the guidelines for the Illinois Livable and Sustainable Transportation Rating System, and we work closely with Hanson’s other disciplines to incorporate sustainable elements into road projects. A good design can accommodate future improvements with minimal to no changes to the design provided today. If we forecast that traffic or truck weights will increase, we can provide a design that easily allows future capacity additions without reconstructing everything. We can also design structures with additional width to provide for future capacity and maintenance without the loss of throughput and capability to handle heavy loads.
Aesthetically pleasing structures without fracture-critical elements provide beauty and safety for residents and users, and we can design structure openings with wildlife crossings and three-sided box culverts equipped with a natural channel bed that reduces environmental impacts. Our team also keeps sustainability front of mind by considering future drainage updates in our designs to reduce construction and disruption during later projects.
- Roadway bridges
Bridges are a critical part of our roadway infrastructure. Quality and dependability aren’t negotiables when it comes to the traveling public. Since our founding in 1954, we have specialized in bridge design, starting with our first job: 56 bridges for the Kansas Turnpike. We have built and provided solutions for bridges at thousands of U.S. locations, from Miami to Fairbanks, Alaska, as well as worldwide.
Whether you are a public- or private-sector client, delivering you innovative and sustainable structural solutions is our priority. From conventional grade separations to major, complex river crossings, we provide comprehensive bridge services, including design, inspection, rehabilitation and load rating for highway and rail bridges. Our complex bridge design experience includes trusses, tied arches, segmental concrete, post-tensioned box girders and cable-stayed bridges, as well as foundations for electrical transmission line river crossings.
Our bridge team, based in offices nationwide, works with Hanson’s asset management partnership, Decision Optimization Technology-United States, to provide customized solutions for your needs while using 3D/building information modeling technology to transform the way we design, build and manage your infrastructure assets. Let us bridge the way to your future.

Sustaining our natural and built environments is a paramount concern for you, and we hear you. Using our experience with the latest modeling techniques, efficient design and policy formation, we assist federal, state and local organizations and private entities in navigating every phase of drainage, stormwater management and flood risk reduction projects.
City of Springfield sewer garage stormwater capture and reuse project, Springfield, Illinois As you face increasing regulatory pressures, budgetary constraints and ever-evolving modeling and design tools, you can depend on us to create adaptive and integrated stormwater management designs and solutions. Our team has the knowledge and experience to understand your project’s nuances and support you through a successful outcome. We integrate environmental stewardship, technical specialization and superior service to provide scalable, innovative and comprehensive solutions.
Our water quality and environmental considerations include several factors, such as treating stormwater as close to the source as possible to reduce the need for extensive conveyance infrastructure, incorporating low-impact development and green infrastructure techniques to manage runoff, using natural elements and constructed facilities to sustainably manage stormwater and monitoring outfalls so they don’t negatively affect receiving waters. We also provide regular maintenance so your system functions correctly and efficiently.
Through our water resources, transportation and sitework projects, we design sustainable stormwater collection and conveyance systems and identify environmentally friendly solutions.

- Transportation planning and traffic
Your community’s transportation system is key to your residents’ livelihood, and it’s not just about roadways — traffic engineering extends to adjacent land and the elements of other transportation modes. Our skilled and experienced team takes a comprehensive view of your transportation and traffic planning needs so you can build a network that will serve your community for the long term.
Technology and innovation are a significant aspect of transportation planning, and we meet your needs with creative and future-focused solutions. Do travelers in your community struggle with chronic speeding or roadways and intersections ill-suited to accommodate a growing population? Do you need better sidewalks, updated traffic signals or more turn lanes? These are just a few of the scenarios we can address to the benefit of your residents and visitors.
As you consider how to position your transportation network for a successful future, trust us to help you form a plan. We can assist you with:
- feasibility studies
- geometric design
- microsimulation modeling
- travel demand modeling
- capacity analysis
- safety and crash analysis
- traffic impact studies
- signal warrant analysis
- geometric design
- roundabout design
- intersection design studies
- signal design
- origin destination studies
- traffic projection
- noise modeling
- traffic management plans (maintenance of traffic)
- Americans with Disabilities Act/Public Right-of-Way Accessibility Guidelines ramp design
- rail interconnect design
- road diet analysis
