Road & Other Closures - Flood

This page will be updated when there are County and municipality-serviced roads and other areas reported to/confirmed by Emergency Management that are closed or have other accessibility issues due to flooding, and when there is additional urgent news. This page is updated as additional closings/issues come in but the listing may not be comprehensive, especially in a high-volume and/or fast-changing rain and flash-flood/flooding situation. Drivers are always encouraged to exercise caution in flood-prone areas near rivers and creeks - turn around, don't drown!
