Transportation Option C
- Similar to B, the freeway and the Marquam Bridge would be
removed from the I-84 interchange to where the Marquam connects
with I-405 on the west side. I-405 would be redesignated as
I-5 (in red). The portion of present-day I-5 north of the Rose
Quarter to the Fremont Bridge would be redesignated as an
extension of I-84 (in green).
- Without any freeway connection on the eastside, improvements
to present-day I-405 would need to be considered to accommodate
the additional traffic volume displaced from the eastbank freeway.
I-405 could be made into a six-lane freeway without widening its
right-of-way through Goose Hollow and NW Portland. On/off ramps
could be removed and consolidated to minimize the merging space
required to get onto the freeway. The long merge lanes existing
today could instead be converted into through lanes for traffic,
making the freeway a more efficient machine for moving trucks and cars.
- A new bridge across the Willamette would be double-decked to
accommodate light-rail, streetcars, peds and bikes on the lower-level
and trucks and cars on the upper level (see light blue).
The bridge would connect to I-5 on the west side approximately
where the Marquam presently connects with I-405 and on the
eastside would pass just to the south of OMSI and meet McLoughlin
Blvd. at a signalized intersection to allow access onto the MLK/Grand
corridor to the north (magenta circle). This would provide local
access from the central eastside and inner southeast neighborhoods
to I-5 in both directions.
