This footage from the WSDOT archives shows construction of the original SR 520 bridge on Lake Washington, as well as construction of the original Portage Bay Bridge, Montlake interchange, Eastside roadway, toll booths, and drawspan control equipment. There's even footage of a sea-plane jet skier on the Lake and guard rail collision testing!
SR 520 is 50 years old on Aug. 28, 2013. Join us on SR 520 Memory Lane to share your memories, read the memories of others, and take a look at historic documents. http://www.wsdot.wa.gov/projects/sr52...
