The U.S. Coast Guard completely reopened the lower Mississippi River with restrictions on Monday, two days after it was shut due to a collision between a tanker barge and tow boat that spilled 656 barrels of light crude oil into the waterway.

The Coast Guard had reopened a portion of the waterway near New Orleans earlier on Monday. As of 1:30 p.m. CST (1930 GMT), the waterway was completely reopened with some restrictions on mariners to reduce the risk they will spread crude oil along the river, the Coast Guard said.

A total of 29 vessels have been delayed due to the spill.

No reports of wildlife covered by the crude have been received, according to the Coast Guard. Cleanup crews have deployed booms to collect the oil in the river.

The 65-mile stretch of the Mississippi affected by the spill is home to seven refineries. (Reporting by Erwin Seba; Editing by Marguerita Choy and Meredith Mazzilli)
