Kansas Department of Transportation—Johnson County Gateway Project

KDOT’s $288 million Johnson County Gateway Phase 2 Project is Kansas’s first and largest design-build transportation project completed in just 2.5 years. The I-435/I-35/K-10 interchange area is a significant transportation hub and economic engine for the region and the state. It is also one of the most congested interchanges in Kansas. The constructed improvements address more than 90 percent of the existing traffic problems in the project area. The Johnson County Gateway Project included reconstruction and capacity improvements within the I-435, I-35 and K-10 interchange area along with improvements at several major local interchanges. A total of 56 new lane miles were added within the interchange area. KDOT made sure to minimize impact to divers during this construction and ultimately delivered a project that cut congestion for drivers (reducing commuting headaches) months ahead of schedule.I-35_95th St Diverging Diamond Interchange.jpg
