CLAY COUNTY — Motorists on Interstate 435 finally have traffic relief as all three lanes in both directions are open as of Friday, Aug. 16, at the Missouri Highway 210 and I-435 interchange, states a release from the Missouri Department of Transportation. Lanes were restricted for the past two year as part of the interchange improvement project to build a new diverging diamond interchange. Work included replacing the old twin bridges over I-435 and Highway 210 and widening I-435.
According to MoDOT, the interchange serves nearly 100,000 drivers per day.
“This project enhances the capacity of I-435 by providing three continuous through lanes in each direction throughout the interchange. Prior to the project, there were only two lanes on I-435 between Parvin Road and the Missouri River. Route 210 is an important freight corridor that serves multimodal freight hubs,” states the release. “... The new interchange accommodates the increased truck and vehicle traffic of Route 210. This project removed the two, uncommon high-speed ramps to enhance driver expectancy and safety. Ramp reconstruction enhances safety by providing increased storage and better turning movements.”
This project also includes the alteration of access at Randolph Road, which will result in fewer traffic signal challenges and will improve safety, states MoDOT's release.
Construction of the project began in the fall of 2016.
