Eh, I take it back -- because this is mapped as a dual carriageway, 
routing across the street won't happen except at valid intersections, so 
there's not *that* much advantage to having the sidewalks as a separate 
way. I'd just connect the steps directly to the road's way without any 
sidewalk. J
