K-7 / Johnson Drive Interchange Receives Outstanding Engineering Achievement Award from the Eastern Chapter of KSPE

A unique interchange at Kansas Highway 7 and Johnson Drive in Shawnee, Kansas, has been honored by the Eastern Chapter of KSPE with the Chapter’s Outstanding Engineering Achievement award for 2011. Partners in the project include the Kansas Department of Transportation (KDOT), the City of Shawnee, Kansas, and GBA. 

The project, which is on schedule for completion in November of this year, will replace a signalized intersection on K-7 at Johnson Drive/55th Street by constructing a modified single-point urban interchange with a large, multi-lane roundabout where ramps intersect Johnson Drive. The project will raise the profile of K-7 over Johnson Drive and will improve K-7 to interstate standards by providing a four-lane divided freeway. Provisions have also been included to add an additional lane in each direction as traffic volumes warrant. Two additional multi-lane roundabouts are being built on Johnson Drive on either side of K-7. 
Accepting the Outstanding Engineering Achievement award are (from left) Howard Lubliner, P.E., project manager, KDOT; Todd Jones, P.E., project manager, GBA; and Doug Wesselschmidt, P.E., Director of Development Services/City Engineer, City of Shawnee.

According to GBA Project Manager Todd Jones, P.E., development along the K-7 corridor prompted the improvements. "The interchange will replace a potentially dangerous signalized intersection that accommodated about 30,000 vehicles each day," Jones said. "During peak traffic, left-turn lane queues backed onto through lanes of K-7, creating safety concerns." When the project is completed, the intersection will handle the projected traffic volume for 2040.

Winners of Chapter awards will be considered for awards at the state level, which will be presented at the KSPE Annual Conference Awards Luncheon Thursday, June 23rd at the Hyatt in Wichita.
