Roxy: Last Stoplight In Wallace

In this 1986 photo, posted by OrangeTV/Remember The Roxy, you see the last stoplight in Wallace — and, if memory serves me correctly, the last on Interstate 90 between Seattle and Boston (h/t: Factchecker). Late mining magnate Harry Magnuson fought valiantly for years to prevent the interstate from bypassing Wallace, as it does now. Ultimately, he lost the battle with progress, and this light came down.

Question: Which survived longest in Wallace — the stoplight of the houses of prostitution?
