All of those roads including the N-S rd. have a marked Bike lane on both sides of the road. It of course could also be used as a breakdown lane . So yes. Pulling over would not be an issue. The N-S has wide shoulders and much distance to the tree line. Cars park or pull off all the time.
Especially when they have seen a moose or a bear! Cars lined up on the side of the road with people out taking pictures. That was always what I expected when I saw cars pulled over.....
