consider dedicated bike trails
I was riding on a bike trail, Busse Woods 7.2 miles, but it used to cross a four-lane with a light.
Not long after my accident, a woman rider was KIA the same location. They have since built a bicycle bridge over the four-lane.
I know just where you mean, I’ve camped in Busse Woods. Sadly a death is often the only motivation that works. We have a trail crossing over a not-as-busy 4 lane and they told us “wait til someone builds out there and maybe they’ll put in a traffic signal”. IOW, commerce is a more persuasive argument than safety.
