I regularly see traffic heading the wrong way on 21st St between Decatur and Hull St. I would guess this happens about once an hour during the day, maybe more often.
This seems to be caused by inadequate signage and by lack of enforcement.
The signage at the intersection of 21st and Decatur should be more visible. There needs to be added signage at the Dollar General exit onto 21st St, there is nothing there to indicate that the road is a one way road.
There have been many times that I have turned onto 21st St from Hull St and had to swerve to avoid a head on collision.
