In theory, you're correct. Unfortunately, all of the bike paths in the area have been effectively privatized by some rather unsavory folks and their pit bulls. They are even doing campfires now. These packs of uncivilized bums at the pinch-points (underpasses and such) of our bike paths is a big part of why Eugene has lost 30% of its cyclists since 2009, imo. I used to see many people ride from north of the river to campus and downtown and they're all back in cars now.

Maybe if all the good people here who are upset by the increased traffic on the Ferry St. Bridge were to call their city councilor and request that the bike paths be kept clear, the cars might move a little freer on the bridge.
