1950s Oregon Road Highway bridge construction 27 color photos clean crisp For Sale

This product is a set of 27 original 35mm color film slides depicting the construction of new freeway and bridge construction in Oregon during the 1950s. Gorgeous color and vivid. I am not positive where some of these are. They might be Portland or Multnomah County, Or even Salem in Marion County. The one slide with a white circle-it helped me date these.
The truck is Chas Wiedeman General Contractor Dallas Oregon phone MA3-2001. I am not positive but with that number this may even be early 50s. Charles Wiedeman had his contracting company from approx 1933 out of Dallas and in 1960 moved to Salem. I located this info by online research and findagrave and obituary. I got these at an estate sale long ago, always thinking they might be Columbia River Highway related. Could be construction of the I-5 but I am leaning towards it being the US Route 99 and later the 5 incorporated Most covered bridges are south of Portland, but at the time there were many more than today.
I took this paragraph from wikipedia The freeway incorporated early bypasses and expressways built for US99 in the 1950s, including a new freeway route from Portland to Salem, and additional bypasses were built using federal fundsNo matter where, the photos are cool if you are into road construction, especially in Oregon. Great shots of autos and men working away like busy bees. Thanks for stopping by
