O'Bunco Engineering International (OEI), along with our trusted consulting partners, has successfully managed numerous traffic and transportation engineering projects throughout the Pacific Northwest. As the population in metropolitan areas continues to grow rapidly, placing increased pressure on already strained infrastructure, OEI recognizes the need for innovative, cost-effective, and collaborative solutions.

We believe that successful planning and land development must be guided by a balance of economics, negotiation, design creativity, and stakeholder compromise. Our team’s expertise ensures that every project addresses both current demands and future capacity.
