Alignment
The freeway would have run from the Willamette River to about SE 50th Avenue adjacent to the south side of Division St. It would then have shifted to Powell Blvd. (Rte. 26) near SE 54th Avenue. By the initial plan, the freeway would have ended at SE 122nd Avenue, though extensions were considered.
In 1962, this section was formally submitted for inclusion in the U.S. Interstate Highway System as part of Interstate 80N, today's I-84.
I-205 itself was in the planning stages at the time the Mount Hood Freeway was first proposed. The I-205 routing was originally envisioned for the 52nd Avenue corridor, but ended up being built farther east at about 93rd Avenue. All plans for the Mount Hood Freeway allowed for a future I-205 connection at various spots.
Another segment of the proposal was called the Mount Hood Expressway. It would have continued the Mount Hood Freeway alignment past a stack interchange at I-205, continuing to follow Powell Blvd. before skirting Gresham to the south and connecting to the existing route.
The final segment of the proposal continued southeast from Gresham and ran to the outskirts of Sandy. This section was actually constructed (and is an expressway-grade highway), with a single interchange at the junction with Oregon Route 212.
