I'm sure it'll be fine, and they'll incorporate several long lanes adjacent to or under the structure for the toll booth backup (like in MIckey & Friends). I just thought with the property (especially where the two existing office space buildings are) being so close to the freeway, it would be cool to have a ramp heading directly into the new structure. Perhaps something banking off over the empty triangle lot (East of the 5) then straight into the structure via the "Arlo" right of way. This ramp would probably go right into level 3 or something. That would eliminate a few (3-5?) traffic crossings/turns for people heading up the 5 (non-carpool lane).
It's merely Jetsons-esque thoughts on my part. No big deal. I should probably be more concerned about how they plan on dealing with getting people over Harbor in a pleasing way.
