HELENA, Ala. (AP) — UPDATE: Colonial Pipeline says it has restarted one of its two main pipelines after an explosion in Alabama, but anticipates that its main gasoline line will remain down the rest of this week.

The Georgia-based company said in a statement Tuesday that it restarted its Line 2, which transports diesel, jet fuel and other products, around 11 a.m. Central Time Tuesday.

Colonial shut down both of its main lines after Monday’s blast, which killed a worker and injured several others.

A Colonial Pipeline leak last month led to gas shortages and rising prices across the South.

After the September leak, Colonial said it made up some of the gasoline shortfall by sending gas through the line that usually carries diesel and jet fuel. The company has not said whether it intends to do so again.

An explosion has shut down a pipeline that supplies gasoline to millions of people for the second time in less than two months, raising the specter of gas shortages and price increases.

One worker was killed and a half-dozen were injured in Monday’s blast in Alabama.

An earlier pipeline leak not far from Monday’s explosion led to Colonial Pipeline to shut down the delivery system in September. That prompted dry pumps and higher prices in Alabama, Georgia, Tennessee, South Carolina and North Carolina.

The effects of the latest disruption aren’t immediately clear.
