Developed and structured specifically for public-sector transportation projects, our transportation design department maximizes the collaboration between our transportation disciplines.

From municipal street widening and pedestrian facilities to major transportation interstates, our transportation design department 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 forms of infrastructure services which includes hydrologic and hydraulic design, roadway design and utility engineering. This ability to yield completely comprehensive services is founded in one of Summit’s key tenants: we design for constructibility and serviceability.

A primary strength of our transportation design department is the direct integration of construction experience into the design process.

Our engineers are all familiar with construction, inspections, contract administration and project certification, so we know what a constructed, landscaped and complete project looks like. This allows us to implement features early into the design that help the budget and schedule later in the process. Our vast number of resources also 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 over 10 years of experience working in the public sector.

Our transportation design department is tasked with the hefty job of getting people where they want to go, but they handle that responsibility without missing a step.
