From the Florida Highway Patrol
Updated at 4:30 PM - US 27 has now closed due to unprecedented flooding from the Santa Fe River.
Please see the attached map and directions for the closure specifics and detour routes.
From an earlier report:
The Santa Fe River under I-75 has rapidly risen 15 feet within the past 36 hours due to the heavy rainfall over North Florida from Hurricane Irma.
U.S. 27, U.S. 41, S.R. 47 and possibly U.S. 121. Additional maps and detour information will be forthcoming.
FDOT and DHSMV have staff monitoring the bridges that may be impacted by the flooding 24/7.
If the river rises to an unsafe level, the bridge will be impassable both northbound and southbound and would be closed immediately. Floridians that are traveling should avoid the area if possible.
If required to be in the area, the Florida Department of Transportation is actively working with WAZE, Google Maps, the Georgia Department of Transportation and other transportation industry partners to communicate the potential reroutes to the public. Floridians should consult www.FL511.com for up-to-date information on road closures and travel routes.
