St. Louis, Missouri: World's Largest Amoco Sign

This gargantuan sign -- the largest Amoco sign in the world-- is located at the intersection of three major thoroughfares: Skinker Blvd. (also known as McCausland), Clayton Rd., and Oakland Ave. It's a stone's throw from Interstate 64 (known locally as Highway 40), just inside the St Louis City limits. The service station is in full operation under the name Stevenson's HiPointe Amoco. Not sure of the sign's actual height, but it is hard to miss. [Jim Dieckmeyer, 04/13/2005]
