About Transpo Group

Transportation systems supply the populace with the means to work, communicate, and travel. As such, transportation planning and innovation must stand the test of time. This is our goal at The Transpo Group — to provide transportation solutions that are sound, secure, smart, and long-lasting.

Since 1975, we’ve offered transportation planning and traffic engineering to both public and private sector clients. As an industry leader, our experience is extensive, our skills are varied, and our attention to local regulation and requirements is steadfast. We approach every project with an emphasis on quality, enthusiasm, and urgency — and our satisfaction rests entirely on that of our clients.

Our People

Transpo Group is headquartered in Kirkland, Washington. Our project teams are made up of highly skilled experts in their field and specialty. Having such diverse capabilities is beneficial to our clients — we’re able to draw from many different transportation specialties, giving us broad perspective for each project.
