Back in the 50’s and 60’s, we used to drive from the Capitol Hill/Burlingame area, westbound, down the Bertha-Beaverton Highway, (Hwy 10), now called the Beaverton Hillsdale Highway and the entrance to the Canyon Drive In was/is now actually the north entrance to Hwy 217! All one has to do is figure out when they designed the freeway, demolished the surrounding businesses and constructed Hwy 217 to figure out the basic closing date of the drive-in. My gut says the very late 60’s/early 70’s. I’d love to see some old photos! I’ll keep looking!
