The Oregonian transportation reporter, Jim Mayer, posed this question about the Columbia River Crossing project as a comment to another post. I thought it was interesting enough to elevate to its own post.
It will be interesting to look closely at the TDM-only alternative to see how it performs. Is it really possible to achieve as much congestion relief with tolling as with any of the build options? Or if not, is the difference worth $2 billion? Same goes for the arterial-only alternative, which the staff tried again to kill off at the last task force meeting. I would be interested in any expert opinion about the fairness of the study methods used to evaluate these two lower-cost options.
Who’s got an answer for Jim?
