Likewise for exit 56 which is at kilometre 57 and exit 48 which is at kilometre 49. You can imagine my surprise when exit 20 happens to be located at kilometre 20!
Why? I have no idea. I merely record it as something a little out-of-the-way that I noticed last night on the trip from Baguio to Manila.
