The Department of Natural Resources staff usually only have to completely block the Katy Trail during tree trimming operations when they are cutting down really big, leaning trees that could crush someone biking past. There is no way to know for sure, but there have been very few posts in the past week about major tree clearing closures so you should be alright.
As far as the Salt Creek bridge washout, it has been dry in the area for over a week and the weather forecast is good, so you probably won't even get wet crossing the concrete low water crossing on Saturday. If you want to see this area beforehand, just go to Google Maps and type in Davisdale, Missouri for the destination. Change to satellite mode and you will see the narrow footbridge that you take from the eastbound direction of the Katy Trail to the Davisdale parking lot, across Hwy. 40, and along the Conservation Road to the concrete low water crossing (it is shown in light gray on the satellite Google Map).
