The 8 lane Fremont_Bridge opened in 1973.

Designers modeled the bridge after the original 1964 Port Mann Bridge in (Greater) Vancouver, British Columbia. https://en.wikipedia.org/wiki/Fremont_Bridge_(Portland,_Oregon)#Design_and_construction
Because the Fremont_Bridge was designed to have 2 decks, it was a far cry from being a 4 lane joke, like the old Port_Mann_Bridge was.
