Colonial restarted its gasoline pipeline six days after an explosion and fire in Alabama during planned work on the line killed one person and injured several others.
Crews continued repair on the pipeline on Saturday and Line 1 resumed service at 5:45 a.m. central time on Sunday.
"Subsequent to today's successful restart, it is expected to take several days for the fuel delivery supply chain to return to normal," Colonial said in a statement.
According to Colonial, fuel products are expected to arrive from Houston to Linden, New Jersey, where the system ends, within three days.
The explosion also shut down a sister pipeline that transports diesel and jet fuel for several hours. The U.S. National Transportation Safety Board is investigating the accident, Bloomberg reports.
