Hi,

It would seem that I added one (or both!!) of the crossings back when the Luas line opened in 2017.

Based on the Bing Streetside, Mapillary and aerial photos:

This crossing appears to exist: https://www.openstreetmap.org/node/6205912947

This crossing (on bridge) does NOT appear to exist: https://www.openstreetmap.org/node/5243916226/

Feel free to consolidate the crossings into one.
