What are the Guardians of Traffic?

The Guardians of Traffic are eight large figures sculpted on four Berea sandstone pylons on the Hope Memorial Bridge, formerly Lorain-Carnegie Bridge, in Cleveland, Ohio. Two sets of Guardians face the east and the other two sets face the west.
 
The artistic style can be described as transitional, between a stylized classicism and the Modernistic or Art Deco style. They were modeled after the Greek god, Hermes. The Guardians have been proudly overseeing the Hope Memorial Bridge since 1932 and have become iconic in the city of Cleveland.
