Five bridges cross the river at downtown Frankfort. The St. Clair Street bridge (known locally as the "Singing Bridge" from the sound of tires on its grated roadway) was completed in 1894, replacing a previous wooden covered bridge. The Capitol Avenue bridge (officially the "War Mothers Memorial Bridge") was completed in 1938. The two newest bridges, which cross the North Frankfort levee, were built in the late 1980s. The fifth bridge, the so-called "Blue Bridge" at the foot of Broadway, is now limited to railroad use.
