Awhile back, both Franklin Avenue and LA City Nerd looked at the differing types of street signs in use in town. Here at QC, we vastly prefer the original dark blue all-caps signs and are suspicious of the new dotted-i signs that have turned up on Western Ave. Honestly, those new signs look more appropriate for a south Orange County exurb than metropolitan central.
Then there’s the intersection of 4th St. and Orange Dr. Sign spotters and urban infrastructure fans take note as this intersection has all three types of signs in one place. The Flickr page has the annotations.
