Similar control cities

On southbound I-75 at Findlay, Ohio, you have an exit (OH 12?) for Columbus Grove and Findlay right before the exit for Columbus and Kenton (US 68 S, OH 15 E, to US 23)

California State Route 57 (Orange Freeway) northbound & California State Route 60 (Pomona Freeway) eastbound both have Pomona as control cities from their southern & eastern start points. CA-57 & CA-60 meet in Diamond Bar & overlap each other for a few miles. The overhead signs show CA-57 North & CA-60 East Pomona. They say goodbye to each other in northern Diamond Bar, but they both reach their control city. CA-57 travels to western Pomona while CA-60 travels to southern Pomona.

In another thread, I mentioned that the Pomona Fwy (CA-60) is inappropriately named because the 10 heads much closer to the center of Pomona (and to such attractions as the County Fairgrounds) than the 60.  But, because of historical reasons, the 60 was named the Pomona Fwy and the 60's co  ntrol city east of L.A. is Pomona.  Part of the reason was that the original names of the freeways were named after the most closely parallel main street near the highway.  Thus, the Santa Monica Fwy was (in the planning stage) known as the Olympic Pkwy, and the San Bernardino Fwy was known as the Ramona Pkwy.  The 60 closely parallels Pomona Blvd in Montebello as well as Valley Blvd in the City of Industry (which used to be known as Pomona Blvd), so it got the name of Pomona Fwy.

Now, the 57 Fwy connects Orange County with the Eastern San Gabriel Valley.  The largest city in this area is Pomona.  And fortunately, the 57 is close enough to Pomona to be a good control city, even though it doesn't hit Pomona directly.  But that's OK in California, where control cities lead you toward a highway towards a highway that eventually gets you to the downtown of your control city.  (E.g. CA-120 in Manteca, CA has a San Francisco control city, I-40 in the Mojave Desert has L.A. as a control city).
If you follow the 57 from Orange County, the 57 and the 60 will merge in Diamond Bar, and then diverge about 2 miles later.  At the divergence point CA-60 has Pomona and Riverside as control cities, and CA-57 has no control city going north. 

I would change CA-57 to have a control city of Glendora north of CA-60, and I would put in two control cities of Glendora and Pasadena on ramps from CA-71 north to CA-57 north and from I-10 west to CA-57 north.  This portion of the CA-57 freeway used to be I-210 and had a Pasadena control city and from points east is the best way to reach Pasadena thanks to the I-710 freeway gap.
