It is sad that Oregon and Washington can’t work together for the good of their constituents and the West Coast (i.e., the I-5 corridor) to get a new I-5 Bridge on paper and build it.
I have an alternative that perhaps was not considered: rather than build a new bridge, build additional I-5 lanes that would allow bypassing the existing bridge and Jantzen Beach area. Build two additional lanes northbound and southbound and leave the current bridge in place.
The southbound lanes could begin around 39th Street area in Vancouver, travel alongside and west of the existing freeway over the river at a height to allow all river traffic to flow underneath it and end somewhere in the area of Portland International Raceway in Portland, where it would merge back into the existing I-5 southbound lanes.
The two additional northbound lanes would follow the same path but on the east side of the existing I-5 Bridge.
