The efficient movement of people and goods is essential to the vitality and opportunity of a community and its citizens. Our team builds partnerships to design transportation infrastructure to shape our communities.
From multi-lane interstates to pedestrian facilities, our transportation design team will deliver extraordinary results on transportation engineering projects. Our professional staff has a wealth of experience, not just in project development and engineering design, but in total project delivery for a variety of clients. We provide all design disciplines for transportation projects, including roadway design, traffic management, hydrologic analysis and hydraulic design, and utility engineering.
Our engineers are all familiar with construction, inspections, contract administration, and project certification, which gives us a unique design perspective. We integrate constructability, serviceability, and value engineering into every project. Our vast number of resources allows us to allocate the right personnel, with the right expertise, to each individual project. With these resources, we combine our flexibility and responsiveness, learned from many years of experience working in the public sector, to ensure successful project delivery.

Featured Project
R-2582A US 158 Improvements
Summit developed and led Engineering for Plans for the widening and realignment of US 158 in Northampton County. This was an 8.5-mile project with 21% trucks, including interchanges with I-95 and US 301. The design consisted of widening the two and three-lane sections of the roadway to a four-lane divided freeway, typically with a total of four roundabouts on the project. Some sections were designed as Controlled Access, while others had Limited Access with a Superstreet design. Summit was responsible for Roadway Design, Traffic Management, and Erosion Control plans for the project. After the project, Let Summit has continued to assist NCDOT with Design and Construction revisions for all design disciplines.
