The tagging isn't great here, as the "Southbank Centre" group relation comes up here on maps instead of the name of the building, which is the Royal Festival Hall

There is a walkway along the road here

This is a public footpath on OSM and OS but the find a route feature redirects walkers around a longer route rather than take this route. Komoot which uses OSM mapping also tries to redirect walkers the long way round. I'm new to OSM and can't see where the issue lies.
