The construction cam is no longer active, which is to be expected, however, the stills and stop time-lapse video are no longer viewable, and that is very disappointing. If you’re nostalgic for the pre-expansion stadium, you can still (for the time being) visit the Portland Timbers Virtual Venue. Holy ephemera Batman, check out the “Jeld Wen” in that uniform resource locator!
Here’s an overhead view from Google Maps that shows the construction from what looks like late 2018 or early 2019.
Since can’t assume the old Virtual Venue is going to remain online in the long term, I’ve archived some screen caps here in case it disappears.
