Should Tijuana be a Control City on I-5 signs in San Diego?

If it was significant enough to warrant putting Tijuana on the signs, I'd expect the roads to back up for miles. Until you actually get past CA-905, I'll bet most people are going to the massive residential developments in that area, and to the Otay Mesa industrial area.

I-5
AADT = 80,000 — Coronado Ave / Otay Mesa Fwy
AADT = 51,000 — Otay Mesa Fwy / Dairy Mart Rd
AADT = 38,000 — Dairy Mart Rd / Via de San Ysidro
AADT = 28,500 — Vai de San Ysidro / Camino de la Plaza (last US exit) & I-805

I-805
AADT = 128,000 — Palm Ave / Otay Mesa Fwy
AADT = 61,000 — Otay Mesa Fwy / San Ysidro Blvd & I-5
AADT = 22,000 — San Ysidro Blvd & I-5 / Camino de la Plaza (last US exit)

Mexican border
AADT = 56,000 — south of Camino de la Plaza

I-5 and I-805 should use Tijuana MX south of California 94. It makes sense. San Ysidro is more of a neighborhood of San Diego, not even a suburb. If you were going to use a suburb in between the 2, I would use Chula Vista.

I'm also still surprised there aren't any advisory signs for Mexico on the 125 between Chula Vista and Otay; maybe because most SB traffic might not be crossing the border.

Flint1979:
I would just use Mexico but that's up to Caltrans. I don't mind how MDOT uses Canada in Detroit.

I just don't get that. After all, I-8 would also get you to places in Mexico (as will I-94 in Detroit get you to Canada) - why not be more specific? It's not like Tijuana or Windsor are obscure.
