Also for road signs that makes a certain amount of sense. It’s a road to somewhere, it makes sense to include that information. But also people would want to know what’s next. Just like on a train announcement, they might say this is a Chiba-bound train, next stop Yokohama.
Near my house there are two interstate 5’s, I-5 North to Seattle, and I-5 South to Olympia. It helps you choose correctly, even though you aren’t going all the way to the destination.
