Work on the Buck O’Neil Bridge/US 169 replacement will cause extensive closures for portions of I-35 downtown beginning in March.

The Missouri Department of Transportation (MoDOT) will close northbound I-35 from 12th Street to eastbound I-70, tentatively beginning Monday, March 7.

The road will be closed for approximately 275 days for construction of a new retaining wall along I-35 and for a new bridge over 6th Street.

Crews will also close northbound I-35 to westbound I-70 during the same period for bridge rehabilitation work.

This is 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 is a triple arch bridge carrying U.S. Route 169 over the Missouri River, serving as a key regional connection between downtown Kansas City and communities north of the river. While safe, the current bridge is nearing the end of its projected service life.
