About Site Development Highways & Bridges Design–Build News Careers Johnson Gateway Project Phase 2 Design–Build, Diverging Diamond Clarkson Construction served as the sponsor for Gateway Interchange Constructors (GIC) – a joint venture between Clarkson (65%), and Kiewit Infrastructure Group (35%) – on the Johnson County Gateway design-build project for the Kansas Department of Transportation (KDOT). This $288 million “set value” venture required the proposer to define the project scope for $285 million with the additional $3 million being an allowed incentive once the project was completed by December 31, 2016 – seven months ahead of the required completion date. Traffic flows were strategically maintained throughout the three-year project – providing minimal delay to the 230,000 travelers that commute through this central corridor daily. Project included reconstruction and capacity improvements from I-435 eastbound to U.S. 69, from K-10/I-435 north to 95th Street, K-10 from westbound I-435 to Woodland Road and northbound I-35 from the I-435 interchange to 95th Street.

The project also included Renner Road, Lackman Road, Pflumm Road at I-435, Pflumm Road at I-35, and College Boulevard from Renner Road to Ridgeview Road. A total of 27 bridges were redesigned/rehabilitated for this project, including two large structural steel flyovers, a large precast concrete beam flyover, eight precast concrete beam bridges, two structural steel bridges and four precast concrete bridges.
