Yes, there is at least one closure with detours. Please go to the home page of this website, then scroll down. On the left you will see "Trail Conditions". That is where the user-reported closures and detours are outlined. You can also go to MO State Parks' Katy Trail page to read the advisories there. Do not let these closures keep you from riding the trail. They are a minor inconvenience when you consider the whole experience.
