As per evidence I have created Sidewalk which is crossing multiple Buildings.

As per latest ESRI world imagery I have created sidewalk which crosses Building , due to narrow space between building and road segment I have to cross the building.

According to Bing Streetside, sidewalks are present on both sides of the Mortimer Market segment at this location 51.52264406398604, -0.13562591928169174. Since this road some portion of the segment are designated as a tunnel, I need clarification: should we also assign tunnel=yes to the sidewalks?"
