Railroad tracks in city streets and the trains who run over pedestrians and run into cars is not very safe. Maybe that is why the tracks end up being pulled up or paved over. Yet new tracks continue to be laid down. See:
Film of removing trolley tracks, Congress Street Portland

“(Sept. 23, 2021) The decades of potholes caused by buried streetcar tracks on N Lombard Street in St. Johns will soon come to an end, when the Portland Bureau of Transportation (PBOT) starts construction on the N Lombard Main Street Repair Project through the heart of Portland’s northern business district.”

The whole Interstate Bridge Replacement project is almost worthless. So long as Portland does not make any serious effort to increase the traffic throughput south of the bridge, a higher capacity bridge will simply “move around” the traffic jam. For example, the “Rose Quarter” segment of the freeway is limited to two lanes — the same as when the freeway was originally built 40+ years ago.

Frankly, the better ‘solution” would be to build the west side bypass as conceptualized back in the 1980s that would create a “mirror image” of the I-205 link (that’s now above capacity in many segments).

Unfortunately, there is a large number of planners and politicians who would rather deny reality and try to force “solutions” on the population that represent their “vision” of some future utopia. (Unfortunately, the definition of “utopia” is “no where.”)

At the last bi-state meeting, the IBR team did not have prepared the capital costs of light rail, which as vastly higher than busses. These costs should be disclosed, how many $???,???,??? per mile are the capital costs to build light rail, which serves only about 1.7% of trips across the bridge and Zero freight?
Vs. Buses in a shared lane with other vehicles including freight
What are the costs of:
Light rail tracks, How many miles are proposed and what is the cost per mile?
Power needed for the overhead lines, and the overhead lines that freeze in winter and overheat in summer, shutting down the MAX light rail.
Light rail trains
Multiple Light rail stations 80′ in the air in Vancouver, WA
Multiple light rail stations in Oregon to extend the MAX yellow line
(so far, the graphics about the elevated freeway in Vancouver seem to be missing from the IBR presentations)
Light rail operations and maintenance costs?

Over a decade ago, light rail hogged about a quarter of the budget for 1.7% of commuters and zero freight. This time, IBR seems to be with-holding the financial information about the $ cost of of light rail.

Given the fact that IBR is plowing thru $$$ MILLIONS of taxpayer funds, the full information presented to legislatures and the public should be far more accurate and complete. The materials seem more like a slick marketing campaign, not full disclosure of the relevant data required to make wise decisions for OR and WA on cost effective options to serve all traffic, including freight..
