Transportation Design & CEI

TTL’s team of transportation design and construction inspection experts have a deep understanding of the intricate connections between the highways, roadways, bridges, hike and bike trails, mass transit, and greenways that make up our extensive transportation infrastructure network. We find a balance between the critical factors that influence complex transportation challenges, continually considering the impacts of mobility, safety, accessibility, efficiency, regulatory compliance, and the environment. Whether expanding federal highways, designing local roadways, developing multi-modal models that reduce congestion, analyzing traffic patterns to enhance safety, or rebuilding a bridge, our solutions are always developed with the end goal in mind.
