The FHP shut down Interstate 10 in Baker County Tuesday morning due to standing water in the road, and dozens of other area roads across northeast Florida are also closed due to flooding.

At 9 p.m., a 50-mile stretch of I-10 remained closed between U.S. 90 in Baker County (Exit 324) and the I-75 interchange. The Florida Highway Patrol and Baker and Columbia County deputies detoured all traffic onto U.S. 90, but urged caution because of pooling water on that road.
