Probably best to take Blvd 2000 from toll road at Popotla. There is now an exit off of the toll road onto Blvd 2000 (you used to have to get off at
Puerto Nuevo or Cantamar and drive north on the free road for a few miles to get there, but not any longer).
I believe it's about 26 miles, and then you need to take the exit to the right for "Tijuana / San Diego".
It's to the west a few miles from there.
The current SENTRI entrance, I believe, is at the intersection where the green arrow is on this map:
