We're always glad to welcome and help new members. And to answer your question about routing: a router is likely to assume that it's possible to walk *along* the length of a highway (unless it is a motorway or has tags prohibiting pedestrians). But if Broad Walk had been mapped with the footway stopping at the edge of the park and then a gap before and after Outer Circle, the router should not assume that it is possible to cross the road at that point. So when mapping footways across a minor road it would be normal to draw in a "virtual" footway across the minor road and a junction node that's common to the footway and the road. Unless further restricted by tags, the junction node would tell a router that it's possible to go straight ahead or to turn left or right. But in this case, the mapper has determined that there is a recommended place to cross the road (the pelican crossing) and has therefore mapped the footway to show a connection via the crossing.
