Here's another example. Look carefully at the letters and you can see the reflector buttons.

Note that this interchange was number 180 in the early days of I-79, when PA had mileage-based exits. It was renumbered to 41. It has since been renumbered back to 180.

I think this is stupid. The exit after 3 should not be 7. Other people disagree. I bet tfabris, Mr "if you ask for coke and get pepsi don't whine" likes it

Someday we'll go metric and we'll have to pay for yet another conversion. Bah.
