MoDOT will be replacing the Baltimore Ave. bridge over I-670. This bridge is nearing the end of its service life necessitating its replacement. The new bridge will be the same height and width as the current bridge. The decorative fence on the existing bridge will be re-attached to the new structure.


This project is being let in January 2021 and construction should begin in the spring of 2021. Construction is anticipated to be completed by December 2021During construction, Baltimore Ave. will be closed at Truman Rd.

There will also be a one time weekend closure for bridge demolition and some lane switches/closures on I-670. This closure is scheduled for the weekend of May 14, 2021.

Motorists are encouraged to use the northern portion of the downtown loop around the closure of I-670.

This work will also close the following ramps during the demolition weekend (May 14-17):

  • The ramp from northbound I-35 to eastbound I-670
  • The ramp from southbound I-35 to eastbound I-670
  • The Truman Rd. ramp just past Broadway to eastbound I-670
