Colonial Pipeline's main U.S. gasoline artery is expected to remain shut through Friday as the company continues to search for the source of a suspected leak in Paulding County, Georgia, the company said in a statement on Wednesday.

U.S. gasoline futures touched their highest levels in three months on Tuesday, after Colonial Pipeline, the largest U.S. fuel pipeline operator, said the main artery moving gasoline from the Gulf Coast to the East Coast was shut because of a potential spill in Georgia.

Emergency workers and crews with the Colonial Pipeline are on the scene in Paulding County responding to a possible gasoline release.
