Workers from a towing service prepare to move a tractor-trailer that overturned when the driver lost control Monday on rain-slicked Interstate 4. Troopers had to close the eastbound lanes near the 22nd Street ramp. An earlier accident involving a tanker truck that hit the guardrail of eastbound I-4 at U.S. 98 tied up traffic in Hillsborough County while 8,000 gallons of diesel fuel were mopped up. The driver, Ronald Roberts of Bradenton, was hospitalized with minor injuries, the Florida Highway Patrol said. Eastbound traffic was diverted off I-4 and around the crash scene for hours. The FHP is investigating both accidents, which come a day after one person died in a 14-vehicle pileup on the interstate. To alleviate gridlock on part of I-4, U.S. Rep. John Mica on Monday proposed building a 52-mile commuter rail extending between Volusia and Osceola counties. The project would cost $38-million to $59-million.
