Welp, I was about 99% correct, but this week they had over 100 correct answers, so no prize:
It’s the John A. Blatnik Bridge connecting Duluth and Superior. It was finished in 1961, when I was about 10, and I remember my first drive over the bridge on the day it officially opened — five kids, mom and dad in the Plymouth, topping out 120 fucking feet(!) above the harbor surface. At that time, it was the highest distance above earth I had ever been. The Blatnik Bridge had replaced a swinging bridge that carried trains as well as cars across the harbor.
As for the exact location and window? 212 Piedmont Avenue [in Duluth, Minn.]
I got right block, but the wrong house. My guess:
I was so sure it was an East Coast bridge that I spent half an hour ranging up and down from Virginia to PEI looking for east-west rivers that a bridge that size could cross. Then I started searching for bridge types, and found https://bridgehunter.com/. Eventually I looked up the Bayonne Bridge to figure out what type it was (steel through arch), and just started looking at all of them, comparing the photos with the VFYW. I’d find one that looked promising, then examine Google Maps to find other features I’d noticed: industry on both sides of the river, the bridge coming to a T intersection on the near side with another highway, a rail yard between the photographer and the bridge, and a Y intersection close aboard to the photo at just the right angle to the bridge.
Once I found the John A. Blatnik Bridge in Duluth, things came together quickly. Here’s the map I drew in my head with my guess about where the photographer must have been (first photo). Then I zoomed in north of the rail yard and started looking for the weird Y intersection that ended in “W **** St” (second photo).
Ah, well. This week's contest looks very French, but I'll find out with everyone else next Friday.
