Sunday marks 23 years since the deadly collapse of the Queen Isabella Memorial Causeway.

A section of the causeway fell after a barge hit it, plunging several drivers over 150 feet into the water below on September 15, 2001. 

Eight people died, and three others were saved.

Port Isabel will be holding a memorial ceremony to honor those who died Sunday at 2 p.m. at the Port Isabel Event & Cultural Center, located at 309 Railroad St.
