While I-75 will remain open, high river waters have closed two other bridges.
"The river is expected to crest at historic and unprecedented levels presenting a potential threat to the safety of travel on this bridge", the department said in a statement.
The river under the interstate rose 15 feet - to 55 feet - from Tuesday to Wednesday after Irma's heavy rains soaked the northern part of the state. That would force the closure of both the north and southbound lanes, hampering evacuees returning home who fled the area due to Hurricane Irma.

The Suwannee River reached 75.5 feet at White Springs when it was measured around 2:30 p.m. Wednesday, according to the Suwannee River Water Management District.
The bridge of concern - a small one at mile marker 408 at the Alachua-Columbia county line - is being monitored around the clock by FDOT to make sure it's still safe to drive over. Anyone planning on traveling to central or southern Florida should consider traveling southbound on I-95, the release states.
This unprecedented river flooding will also cause closures and extensive rerouting of traffic on USA 27, US 41, S.R. 47 and possibly USA 121.
