I am on the north side of O’Fallon as well. Salt River Rd. was open this morning (suprisingly). However, all the farm land north of Salt River Rd. is flooded. It looks like a lake from the top of the Highway 79 overpass going into Old Town St. Peters.
We are over to the west, behind St Dominic High School. If we go under, I'm building an ark cause the whole world is going under at that point!
