Paul,
Thank you for your brief discussion regarding bicycle amenities around town versus freight. So much of the time we pit bikes, pedestrians, commuters and freight needs against one another when it takes all of these to make a successful city. A concept that is getting popular around the country is to let private industry construct private bridges for freight needs, that service freight destinations directly and usually more effeciently than commuter corridors. Several examples have been implemented on the East coast and might be worth evaluating for Portland. Perhaps a new freight bridge would allow bike lanes on the St. Johns bridge?
