The problem is not providing better access. That's what the populace might want. The residents, who are already happily interfering and obstructing, illegally at times, don't want that, and certainly don't want the idea of 'night access'.
The problem is providing better access without limiting access for the police or fire men.
So you need to provide a parking lot and a dedicated trail to make sure people can reach their goal (seeing the sign in person) without going through the neighborhood itself.
