The U.S. Army Corps of Engineers is warning boaters that they could be delayed at Lock and Dam No. 2 on the Allegheny River near Highland Park because part of the lock wall has collapsed.

A 180-foot section of the crumbling wall near the shore can't be used for mooring because it's too dangerous, the Corps said, especially after a 10-foot piece of concrete recently fell off into the water.

Boaters may still tie off on other sections of the wall and may be asked to raft off each other if they fill up all the available mooring hooks on the part of the wall that can still be used.

The Corps plans to close all the locks on the Allegheny for 21 days in mid-September to make repairs, although the wall at No. 2 had not been part of that original schedule.

The Corps said it hopes to be able to find some money to include it in the repairs.
