U.S. Highway 40.
For some reason Missourians (Who mostly also pronounce Missouri wrong) say 40 Highway for Highway 40. They also do this for the other numbered state and U.S. highways, e.g., 71 Highway, 50 Highway, 7 Highway, etc. I have no idea why they do this, and I have come across no other group who does this.
