Here are a few pics I got today (April 8, 2022) while tying up loose ends to clinch some road segments.
1. This is in Poway, on Pomerado Road (Historic US 395) facing south toward the intersection with Poway Road (San Diego County S4). I don't know what the "T" and "S" letters on the sign refer to - maybe these are wildfire evacuation routes? {other signs in the area also have an "R"}

2. This is in Santee; the sign is on westbound Mission Gorge Road. Note the older SR 52 sign in button copy.

3. This is near the City Heights section of San Diego, facing west on El Cajon Blvd. a/k/a "The Boulevard". This route is signed in places for Historic US 80, but note in this picture a blue/red I-8 Business Loop sign. This is also an intersection with Historic US 395, which headed north (right) on Fairmount, and continued west as a multiplex with Historic US 80.

4. "The Boulevard" and Fairmount facing east, with an Historic US 80 sign on the pole at left.
