Living in Southern California for the last 20 years, I've gotten pretty used to the roads, and it was helpful when a couple of toll roads were put in to bypass some of the particularly bad traffic on the the freeway.
These roads have far more limited access than the usual highway, so it seems inconceivable that these two connected thoroughfares could have three exits with the same name, but that's exactly what happened: there are three exits for Portola within about eight miles of each other.
I don't know about everybody else, but it took me a long time to really remember the difference between the similarly-named 241 and 261 tollways, and in a kind of perfect storm, I used to live near the 241 Portola and had to routinely visit a place off the southernmost 261 Portola.
I just can't imagine how many people have gotten lost due to this poor design (which inevitably leads to imprecise directions), and it's hard to believe that there couldn't have been a way to remove at least one of them (for instance, putting an exit at Bake instead of the southernmost Portola would have been helpful).
If there's a good reason for this, I'd sure love to know it.
Note: this is not a recent development, but it's just taken me a while to get around to writing about it.
