I-10 Business Route in Pomona, Ontario

WARNING: This is a pure roadgeekery post. Those of you not roadgeeks will find nothing of interest here.

I was intrigued by AARoadtrips' page on Interstate business routes, particularly his notes on some local business routes, since I didn't have much of a recollection of seeing many business route signs around here. In particular, he notes that the I-10 business loop along Holt Boulevard in Pomona and Ontario is decommissioned but still has some remnant signing. I was out near that area this morning anyway and decided to follow the route in its entirety to see how much signage remained. Answer: Not very much at all. No signage at all exists to direct drivers from the mainline freeway to the business route, and the signs that remain are all within a mile of each other in central Pomona, even though the route supposedly exists for about 12 miles.

Here are photos of the remaining signs. First, a detail of the sign design:

Next, the only eastbound sign, between Park Avenue and Gordon Street:

Next, the first westbound sign I saw, just west of Towne Avenue:

Another westbound sign, between Garey Avenue and Main Street:

The last westbound sign, just west of Park Avenue:

So there you go. One mile signed on a 12-mile route! I might try finding the business route that goes from Fontana to Colton sometime soon.
