Johnson County Gateway Interchange
The Johnson County Gateway Interchange, where I-435, I-35 and K-10 converge, is one of the Kansas’ busiest corridors and one of the Kansas City area’s economic engines. With traffic demands and congestion steadily increasing, KDOT saw an opportunity to reconstruct the interchange using the design-build delivery method.
As part of the design-build team, TREKK led both design and construction survey along the entire project limits, which included 27 bridges and 56 new lane miles. Our LiDAR team collected mobile LiDAR scan data along 36.5 lane miles. We designed pavement marking throughout the entire interchange.
TREKK was also responsible for drainage design at several locations, including the diverging diamond interchanges at K-10 and Ridgeview Road and I-35 and 95th Street, the service interchanges at Renner and Lackman roads, and along I-35. We designed drainage improvements along College Boulevard, which was widened in conjunction with the Gateway project.
Now complete, these improvements have increased safety and eased congestion through the many intersections in this travel hub.
