More like a few decades.
Several million dollars have been spent on the i/5 bridge replacement plan already.
By 2024, that figure should be approaching a billion dollars.
Well over a billion easy, since we are looking at crossing a major river high enough to allow ocean going traffic to pass underneath.
I always took the freeway through there the few times I go to Portland from Seattle - yeah that bridge isn’t the best. A few months ago I took a back road to the west of Portland heading north along the west side of the river.
Really nice drive once I got out of Portland suburbia - never been that way before.
