The Mississippi River is reopened near Granite City, Illinois, after clean-up operations at Lock and Dam 27 were completed, Friday.
An auxiliary lock was opened at the Lock and Dam 27 site for commerce to continue.
The towing vessel Gregory David was transiting the lock and dam, and was damaged, rupturing a tank with approximately 20,000 gallons of fuel aboard. The spill was reportedly contained within the lock.
The cause of the incident is under investigation.
