Check out Bismarck Memorial Highway. The promoters put the pop-up trail on the westbound driving lane, striped it, placed hay bales and orange cones to create a 6-foot trail. I was told the sidewalk by Zonta Park was too narrow. I measured it and it is also 6 feet.
That makes the traffic lane too narrow. Cars usually travel 45 mph or even more there. I live there and we have not seen even one person on the trail. Walkers who live in the area do not walk in the street lane.
Farther west, on Summit Boulevard, the path takes the parking lane instead of the sidewalk. Apartment renters need that parking.
Do not design a dangerous pop-up path. Make them safe ones on existing sidewalks, not in fast traffic like Memorial Highway. Work with city traffic designers, do not make it a do-it-yourself plan.
