Project Milestones
Crews will post various daytime and nighttime lane closures for the rest of the summer for paving operations.

Updates are also included at the bottom of this website.
Big changes coming to eastbound I-435 between State Line and 3 Trails Crossing starting tomorrow! Starting at 9 a.m., one lane will be dropped headed eastbound and stay that way through rush. By the end of the weekend, you will be in an entirely new traffic pattern, similar to what's happening on the westbound side.
The new configuration overall will be two lanes on the inside and two lanes on the outside with the ongoing work occurring in the center. Traffic from I-470 westbound and I-49 northbound will have access to the 103rd Street, Holmes and Wornall exits through the two outside lanes only, so merge into the outside lanes immediately after the I-470 ramp bridge comes to an end.
Missouri Department of Transportation is moving into the next phase of the I-435 South Loop Link Project starting this weekend. Beginning Friday, Nov. 16 at 7:30 p.m. through early morning on Monday, Nov. 19, the right two lanes of westbound I-435 will be CLOSED to finish concrete paving, pavement striping and to move traffic into a new driving configuration. In addition, the westbound Holmes Road entrance ramp will CLOSE Friday, Nov. 16 at 10 a.m., and the westbound Wornall Road entrance ramp and westbound State Line road exit ramp will be CLOSE Friday, Nov. 16 at 7:30 p.m.
Construction on additional lanes and bridge improvements began in Spring 2018. This is part of Phase I of project construction.
Crews began on Phase 1A plans in May 2018. This phase is scheduled to last through the end of fall.
The project begins moving into Phase 1B in August as crews prepare for the next round of paving and bridge work. Download plans for Phase 1B here: /media/15772
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.
