Semi-Trailer Damages Bridge from Michigan to Canada [PHOTO]

Oh buoy! Sorry, the pun was just sitting there. 

A semi-truck hauling a buoy underneath the Blue Water Bridge between Port Huron and Sarnia didn't quite make it out unscathed.

The buoy dragged across the under-side of the bridge around 9 AM yesterday and, in the process, broke off some large chunks of concrete before becoming stuck.

MDOT says that inspectors are assessing the damage to the bridge, which appears to be cosmetic and not structural. Law enforcement says that citations will be issued to the driver.
