A well-known Missouri trail will be closed for some bridge improvements after the Memorial Day holiday. MoDOT has announced the southbound 63 bridge over the Katy Trail in Callaway County will be widened and receive a new deck. The bridge, just north of Jefferson City, will cause both southbound lanes of 63 to be closed for several months. The northbound lanes will be converted into a one lane road for both directions of traffic. During the work, occasional full and partial closures will occur on the Katy Trail during weekday hours.
