Committed to Connecting People and Communities

The flow and movement in Transportation have come a long way. Literally. If it weren’t for the concepts that went into designing better and more efficient roads, we wouldn’t be able to travel safely to get to our destinations and everything that connected to them. Our team of skilled engineers has designed the most driven roads in the valley, partnering with multiple municipalities to provide corridor studies, transportation planning, roadway design, and traffic engineering.

We offer expertise in public and private infrastructure projects from the preliminary planning stage through final design for urban freeways, traffic interchanges, rural highways, major arterials, intersections, local streets, and pathways. At Dibble, we deliver streetscape and complete streets expertise for multi-modal users and ADA compliance. Our team has qualified staff, dedication, experience, and passion for successfully designing your project with the ability to provide construction management and value engineering opportunities.
