The I-435 South Loop Link

This project was completed in May 2020. The I-435 corridor was constructed in 1966 as a six-lane freeway and an additional lane was added in phases from 1983 to 1994. This segment of freeway provides an important link between residents and jobs on the south side of the metropolitan area. I-435 has become one the highest traffic volume of any MoDOT facility in Kansas City and one of the highest in traffic volume in the metropolitan area.

The project’s primary purpose was to maximize the safety and mobility for all traffic along the I-435 corridor from the Three Trails Crossing to the State Line, as well as minimize future maintenance needs. This more-than-three-mile project replaced the bridges at Wornall and Holmes, rehabilitates the bridges at 104thStreet and the Blue River, and upgraded the pavement on I-435 which included adding another lane.

Additional improvements included removing the loop ramps at the Holmes Road Interchange, 12 foot inside shoulders along I-435, increased vertical clearance under the Wornall road bridge, new taller and safer concrete barrier wall and longer merge lanes in critical locations. This project will finish in Spring, 2020.
