As with a number of Astoria's streets, at this point 16th Street doesn't have the support of solid ground. The intersection in the first photo is just to the left out of the picture. It's hard to see the concrete wall a few feet behind the pillars, but it's there - and it's impossible to see beyond the concrete wall to know what the structure would look like under the intersection.
For those not familiar with Astoria, Oregon, Marine Drive is at the right of the photo, with the River Walk and the Columbia River just a few paces away. The mountains are in Washington, four miles across the river. The purple building in the middel is Custard King, and on the left is Shallon Winery, which I have not shown yet. To reach downtown Astoria, travel left on Marine Drive or enter the one-way grid in the top photo.
