Have You Ever Wondered: Why Is The Freeway Name This Way?

LA PUENTE - If you are one of many regular commuters who drive between Los Angeles and Orange County and the Inland Empire, have you ever wondered why State Routes 60 and 91 have the names that they do?

Why is the 60 freeway named The Pomona Freeway when it goes well past Pomona and directly into downtown Riverside?

Why is the 91 freeway called The Riverside Freeway when it does not go into downtown Los Angeles, but through Orange County? 

The 91 somewhere along the L.A. and Orange County line kind of becomes The Artesia Freeway. Seems to have made more sense to name it The Torrance Freeway.
