Which is the Junction?

Unusual placement of Junction banner at California 58 and 229

A reassurance assembly and a junction assembly were combined for eastbound traffic on California 58 at California 229 in San Luis Obispo County when this photograph was taken in November 2009.

Note that traffic on California 229 does not stop for California 58 traffic. Westbound traffic on 58 has a stop sign, hidden from this view. In practice, I observed most drivers treating it like a yield sign (i.e. "rolling stops").
