I've been amused watching the conniptions of our local politicos about the two most significant obsolete portions of our local freeway system: the Interstate Bridges and the Rose Quarter section of Interstate 5. I sense there's a lot of overlap between those who are pushing to replace the two three-lane Interstate Bridges with two new three-lane bridges (on the one hand) and those who oppose widening the two two-lane sections of Interstate 5 where the Rose Quarter has grown up around it. That section of Interstate 5 is the only urban section of Interstate 5 between Canada and Mexico that hasn't been widened to six lanes - even in Eugene, Salem, Ridgefield, and Castle Rock (population 2,234) this vital commercial link has six lanes.
I've read only one sound objection to improving the Rose Quarter section to match the rest of the urban freeway, which is that Harriet Tubman Middle School is next to the freeway and widening the freeway would make the air quality at the school even worse. I don't begrudge that objection - the school was built in 1952, 14 years before the freeway opened - but it's sometimes occurred to me that the school district might have noticed the freeway's presence before it put millions of dollars into remodeling the building a few years back, and perhaps even considered moving the school to a new location farther from the freeway.
