The Santa Fe River has rapidly risen 15 feet within the past 36 hours due to heavy rainfall over North Florida from Hurricane Irma, and could force Interstate 75 east of Ft. White to be shut, according to the Florida Department of Transportation.

If the river rises to an unsafe level, the bridge will be impassable both northbound and southbound and would be closed immediately, transportation officials said. Additional bridges that may be impacted include those along U.S. 27, U.S. 41, Florida 47 and possibly U.S. 121. The attached map shows potential detours around the affected section of I-75.

State transportation officials are monitoring the river’s flood stage to see if it impacts bridges along the interstate as well as on nearby state roads.

For now, Floridians traveling in that area should avoid it if possible, state officials warn. And in the event that I-75 closes, multiple detours will be set up.The Florida Department of Transportation is working with WAZE, Google Maps, the Georgia Department of Transportation and other transportation industry partners to communicate potential detours to motorists. Floridians should consult www.FL511.com for up-to-date information on road closures and travel routes.
