>>1007612They have bike lanes in that manner in other parts of the metro but it's not very popular. (Top left picture) There is a serious winter season and when the snow starts to creep from the grass to the street then the bike lane disappears. If the bike lane is inside of traffic as shown there is more space available for cyclists when roads narrow in the winter.
I was a little lazy and didn't represent the grass/trees completely accurately. The space is actually narrower and, as is typical in our region, the trees are placed in the center of the grass. (Top right picture.) 6 feet is plenty of pedestrian space for this area. The space alternates from grass to pavement depending on the building use along the street as you can see in the pictures. A coffee shop uses the side street for their patio space. (bottom picture)
