The exact proposed route of Interstate 105, Century Freeway?

[ACSCmapcollector]

I know that Interstate 105 is known as the Century Freeway, or the Glenn Anderson Freeway.  Many opponent would not want it to go to Interstate 5, the Santa Ana Freeway or eastward to the CA 91 Riverside Freeway, why not?  Is this segment of freeway really NIMBY, Not In My Back Yard?
