Several other airports number their runways in this fashion when they get above two runways. I know Atlanta has 5 runways numbered as 8L/26R, 8R/26L, 9L/27R, 9R/27L, 10/28, even though they are all at 94/274 degrees. I'll have to pay more attention the next time I have a flight into ORD, hopefully not soon
