Traffic Alert: Look for long-term closures as part of the Buck O'Neil Bridge Project

CLAY/JACKSON COUNTIES – The Missouri Department of Transportation will make the following traffic changes, some of which will be long-term closures. This is all part of the Buck O’Neil/US 169 Missouri River Bridge replacement project. All work is weather dependent.

Crews will close the right lane of westbound I-670 between Oak St. and I-35 from 5:00pm, Sunday, March 13 until 6:00am, Monday, March 14 for signing work

Crews will close the ramp from westbound I-670 to northbound I-35, beginning at 7:00pm, Sunday, March 13 and lasting approximately (275 days) nine months for bridge work

Crews will close two right lanes of northbound I-35 at I-670 from 8:00pm until 11:00pm, Sunday, March 13 for signing, and pavement work

Crews will close two left lanes of northbound I-35 at I-670 from 11:00pm, Sunday, March 13 until 6:00am, Monday, March 14 for signing and pavement marking work

Crews will close northbound I-35 at the 12th exit from 12:01am, Monday, March 14 for approximately (275 days) nine months for bridge reconstruction work


***Note: The above closure will also include all ramps past the 12th St. exit from northbound I-35 to Broadway Blvd., and westbound I-70 and eastbound I-70. 


This is all part of constructing a new Buck O’Neil Bridge that can be reasonably maintained, while providing a safe, connected, and accessible transportation facility that improves system performance.   


The new Missouri River Bridge will cost close to $220 million dollars to construct and expected to be completed by 2024.


The current Buck O’Neil Memorial Bridge is a triple arch bridge carrying U.S. Route 169 over the Missouri River, and serves as a key regional connection between downtown Kansas City and communities north of the river. While safe, the bridge is nearing the end of its projected service life.




Motorists are reminded to slow down and pay attention while driving in work zones. Not all work zones look alike. Work zones can be moving operations, such as striping, patching or mowing. They can also be short term, temporary lane closures to make quick repairs or remove debris from the roadway.
