Gate Cracks Close Dubuque Lock & Dam 11

Cracks in a gate at Dubuque's Lock and Dam No. 11 have shut down commercial river traffic on the Mississippi River, according to the U.S. Army Corps of Engineers.

Lock Master Gary Kilburg told our coverage partners TV9 workers found the cracks in the anchorage of a mitre gate during a routine inspection Tuesday morning. Miter gates are comprised of two leaves that provide a closure at one end of a lock. The Corps of Engineers is preparing to replace the gates soon.

Kilburg said it will take a couple days to make temporary repairs. During that time, nothing may go through the lock.
