The Edmund Pettus Bridge in Selma is now on the National Register of Historic Places, the U.S. Secretary of the Interior and National Park Service released Monday.

Civil rights marchers trying to draw attention to the need for voting rights legislation on March 7, 1965, were attacked by law enforcement officials as they crossed the renowned bridge.

Known as “Bloody Sunday,” the attack contributed to the passage of the Voting Rights Act of 1965.
