Interstate 435

Home » Guides » Kansas » Interstate 435

The Kansas side of the Interstate 435 beltway encircling the Kansas City metropolitan area joins suburban areas of Johnson County to the south with the Missouri River bridge into Parkville, Missouri to the north. The 28.03 mile route through the Sunflower State provides a bypass for travelers north to I-29 and St. Joseph, the Kansas Turnpike west to Topeka and I-35 southwest to Wichita. The Johnson County stretch through Lenexa, Overland Park and Leawood is a heavily traveled commuter route with 2015 traffic counts topping out at 144,000 vehicles per day by the Missouri state line.

Historically Interstate 435 was planned as a east side beltway around Kansas City for Interstate 35 between Lenexa and Claycomo, Missouri. The west and north portions of the loop were constructed to 1986.

A three year, $165 million project improved Interstate 435 through Overland Park. Construction expanded the freeway and improved access to Corporate Woods and the College Boulevard corridor by reconfiguring the interchanges along the U.S. 69 freeway and adding ramps with Antioch Road (Exit 80). The final component finished was the flyover ramp from U.S. 69 south to I-435/U.S. 50 east, which opened to traffic on December 11, 2008. Work was slated for completion on December 31, 2008, but fabrication errors in plates used to connect the steel girders on the flyover added a delay.1

Ramp meters were implemented along an eight mile stretch of Interstate 435 in November 2009 as part of a $400,000 pilot project. The meters operate at on-ramps from Metcalf Avenue (Exit 79) east in Overland Park to Wormal Road / 103rd Street (Exit 75B) in Kansas City, Missouri.2

The I-435/U.S. 69 Interchange Improvement "Red" Project followed from July 2011 to November 1, 2013. Costing $102 million, this work added collector distributor roadways along U.S. 69 south from 103rd Street to 119th Street and Interstate 435 between I-35 and U.S. 69.3

The Johnson County Gateway project further upgraded Interstate 435 at the confluence with Interstate 35 and K-10 in the city of Lenexa. Estimated to cost $600 million, the three phase project rebuilt the cloverstack interchange at I-35 and I-435, added distributor roadways linking I-35 south with K-10 west and from K-10 east to I-35, and reconfigured the semi directional T interchange between the beltway and K-10. Phase 2 commenced in Spring 2014 and extended through January 2017. Phase 3 work will add c/d roadways linking K-10, west of Renner Boulevard, with I-435.
