The bridge by Mill River St has lights but they're only turned on at night. It's kind of a long bridge, so it's always pretty dark under there. I use this route when riding my bike to work, and I always fear that a car won't see me or I'll hit a pot hole or other indentation while I'm riding. Usually I wait for cars to pass before I go under, but I still worry that a car might come speeding through and hit me. A simple and safe solution would be to keep the lights on all the time.
