Federal megaproject funding will not occur on any major project anymore unless there is a dedicated transit piece. The two options in this case were Light Rail, or Bus Rapid Transit, which would actually have been more expensve and occupied the same amount of space on the bridge. Going from the separate light rail bridge to the in structure design, which admittedly looked cool, was a stupid idea, because otherwise they could have "delayed" that part of the project forever and still got the needed funding. It wasn't that pro mass transit people snuck that piece in, its a requirement for federal funding. The gas tax was to fund about 300 projects statewide, not just the bridge. Borrowing rates on bonds being what they are right now, not building this project right this minute is criminally neglegant. Light rail, and transit theory itself is one of those things that you can literally debate either way for days and still manage to come to 4 different conclusions each time you try. I've heared all the arguments over the years of this project (interesting fact, if you look for any of the televised meetings, you can probably find me in the background somewhere running the audio components. 30+ simultaneous live microphones in the same room with broadcast audio less than 4 feet away and minimal feedback, and they said it couldn't be done! or wait, that was "shouldn't"...), but you're right. light rail fare, as a standalone entity will never pay for itself. the argument beyond the requirement for federal funding for the project, mainly boils down to every single person who rides light rail is one less car passing over the bridge structure, which can only support so many simultaneous cars for demand, but also only so many cars over the structure before it requires repaving. Bridge paving is typically quite expensive, so if you can reduce that significantly you do see a substantial savings on maintenance. The counterargument being that those people were going to ride anyways, so there is no real savings. The other argument is that a major transportation project, acccording to "Environmental Justice" rulings at the federal level, "Always unfairly impact low income individuals and must be mitigated." Offering a mass transit piece counts as part of that mitigation effort, etc. So you're really damned any way you look at it. Don't put one in and you can't build it because half your federal funding is gone and you get sued by suprisingly lawyer equipped poor people. Do put it in, and you get people who correctly notice that the cost of a light rail ticket would need to be about $1,541 per ticket to actually pay for itself. Putting the light rail structure inside the box girder of the main bridge itself actually dramatically reduced the overall cost, because you have to pay for that structure anyways to support the car bridge, so really you were just paying for track, electricity and rail cars, and maybe a 1-2% structural increase cost, which would have been negligable.
The other thing that everyone siezes on is the bridge height issue. Everyone is all "those idiots didn't even talk to the coast guard LOL1111!!" the problem that everyone semes to forget is that there was a new cost guard comandant that came in with the Obama adminsitration. The bridge height and permit issues were already "settled" with the previous commandant, and letters of understanding were sent, etc. pending the final permit which couldn't happen until after the final environmental impact statement was filed, etc. That all went out the window with the new guy who immidiatly said he wanted the bridge raised. The FAA basically came back and said "go **** yourselves Coasties, we got 2 airports that say no to raising it any higher" and so the project looks like idiots through in that particular case no fault of their own.
That city plan article is interesting. There is no way that either vancouver or portland could fund that on their own, even with federal grants. They just couldn't come up with enough matching funds, and portland has others they might consider first, but I could see them coming up with enough funds to keep a project office open for a while. That being said, I do know somwhat more at this point regarding the fate of the current project and what might come out of it, but I'm not at liberty to really mention any of that for now. all is still interesting times for sure...
