Down by the water? Lovers, muggers, and thieves?
Seriously though, it's frustrating how often this comes up for an explanation why why can't have nice things. "Unsavory characters" is why we don't like building public spaces, there are no public restrooms, and benches are uncomfortable everywhere. Other places seem to try to fix the root problems. We often seem to just give up on building nice public spaces.
There's a
similar tunnel under the next bridge upriver, and it's fine. Biking right along SFR is unpleasant. I'd love an underpass at this bridge.
