When taxiing from 26L towards the terminal I crossed 4L/22R. I noticed that the taxiway sign indicating the runway entry is the wrong way around. It shows "22L/4R" - which is wrong, it should be "4R/22L" as the threshold of 4R is to the left, 22L is to the right. This is true for all taxiways crossing 4R/22L heading towards the terminal, with the cargo terminal "in one's back"
However, the signs are correct when taxiing towards that runway from the terminal (heading 137). Also, the signs are correct for the parallel runway 4L/22R.
Would be great to correct that small error. Maybe also check ground markings whether they are correct.
Otherwise this is a WONDERFUL airport. Thanks a lot!
