About The Event

Garrett Hummel and Nicholas Thomas of Wilson & Company will be presenting along with Steve Rockers and Nathan Jefferies of KDOT on the 75th St. & I-35 Street project. The presentation will begin at noon and last for about an hour. 

Project Description:

Wilson & Company was contracted by the Kansas Department of Transportation (KDOT) to design the addition of a 4th lane to I-35 through the 75th Street Interchange in Johnson County, Kansas. The project consisted of widening southbound (SB) I-35, widening and reconstructing northbound (NB) I-35 including lowering the profile of NB I-35 to achieve 16’-4” vertical clearance on the outside superelevated shoulder under the 75th Street bridge to allow commuter buses to utilize the shoulder during rush hour. The addition of the 4th lane required the realignment of all three of the 75th Street ramps requiring three retaining walls, two MSE retaining walls totaling 1,314 linear feet and one 496 linear foot cast-in-place retaining wall. The project featured a well-developed MOT approach that maintained 3-lanes of traffic in both directions during construction.
