A year before its completion, the bridge was named in honor of Francis Scott Key who wrote the Star-Spangled Banner in 1814 while watching the British naval bombardment of Fort McHenry.
A buoy in the colors of the U.S. flag marks where Key's ship was during the bombardment, about 100 yards away from where the bridge now stands.
The Key Bridge carries more than 11 million vehicles each year.
