GBA was a major participant in KDOT’s first major design-build project. This interchange handles more than 230,000 vehicles daily with the major intersection of I-35, I-435 and K-10 serving as a transportation hub and economic engine for the region. This project’s goals included meeting the traffic demands of the interchange for today and tomorrow, improving safety, sustaining economic development and replacing declining infrastructure. GBA provided bridge, traffic and roadway design services, and designed 15 of the 26 structures involved in the project, as well as utility coordination and intelligent transportation features.
