I have a question; more pretaining to a lack of bike lane then the presence of one;
If the bike lane 'runs out' say in front of a small bridge or some such, and the 'Bicyclists on Roadway' sign is there, I know technically Oregonian cyclists are fully allowed to take to the lane (some suggest even taking the entire lane for safety reasons, so cars don't pass where they wouldn't have room to safely do so, etc)
BUT
how is one expected to do that when on a bike where your max speed can top out around 16-18 mph without honestly getting run over/beaten/abused/etc? I'm asking now because if I get either of my prospective jobs now, I'll be commuting over such a bridge 2x/day, and I don't want to get killed on my way to work, and I don't necessarily trust most local drivers, either.
