Is this path still closed?

Is NCN 3 signposted to the station? It's not marked on Sustran's map

Is there still a WHSmith shop located here?

Sustrans map has Baldwin St as NCN 4 so now avoiding Queen Charlotte St & Queen Sq.

Have they updated the signs?

It looks like canopies, which pedestrians can walk under, have been mapped as buildings. There is no building cut back at this point.

Has the A road reference actually been rescinded?

Is this access road for the station construction still in use now it's complete & open?

NCN 4 - does it route along Ffordd yr Harbwr now?

Is this toucan crossing in use?

Need to confirm:
From the signage it appears Colston Av & Broad Quay are one way heading South for taxis, but only if they pick up at this rank:
osm.org/node/4835523530
The adjacent road is only one vehicle wide & is just a glorified taxi rank. so no overtaking if there's a queue.

There is no 'through route' for them.
