Officials are evacuating more than two dozen homes near a train derailment that occurred two weeks ago in southwestern Jefferson County.
People are being ordered out to allow workers to remove hazardous chemicals from some of the tanker cars.
Part of Dixie Highway is closed and nearby Ohio River traffic is being stopped while the chemicals are removed.
31 homes within a half-mile of the derailment are being evacuated.
That evacuation could last three to four days..
