Officials Reopen Stretch of I-4 in Florida

Florida officials reopened a stretch of Interstate 4 late Thursday that had closed earlier this week following a massive traffic pileup that killed four and injured dozens, the Bradenton (Fla.) Herald newspaper reported.

Dozens of vehicles were involved in the crashes that closed much of I-4 between Lakeland and Haines City, Fla., the paper said.

State investigators are looking into the causes for the accident.
