ST. JOSEPH, Mich. -- St. Joe Harbor Harbormaster Mike Moran is reporting the Bicentennial Bridge suffered a mechanical failure late last month that left it unable to be raised. 

Motor vehicles crossing the bridge will not be impacted, but large power boats and almost all sailboats cannot currently fit under it.

"They are doing repairs right now—and hope to have them complete by tonight—-but there is a chance it could impact the 4th of July holiday weekend," and MDOT officials said.

The bridge has eight hydraulic cylinders in total, four of which were just replaced last winter. The other four were scheduled to be replaced this coming winter, but one of those four has broken. 

Fireworks closures of the bridges and channel will be coming on July 3.
