Many subdivisions in suburban communities since the 70's are built off major feeder highways and without sidewalks. The development itself may be safe to walk around in because of low volume of traffic but it's impossible to safely cross the often 6 lane road and even if your destination is right across the road from your subdivision you take your life in your hands trying to cross it.
Older towns build before the 60's were built in a smaller scale with interconnecting minor roads.
Even places that are a mix, if your destination is in the later developed part of your town, you probably won't be able to safely walk to it because the road engineers and the town planners deliberately designed it for car access only, so you could have a destination a short distance away that you must get into a car just to cross the street.
This exists all over the country.
So you have no crosswalks across six lane highways, and no sidewalks along those roads. Is that what you’re saying?
Also, are there stop lights at any of the intersections of those six lane highways?
