this thing

[i realize in hindsight that I could've used D15-1 signs for some of these. also that it's not important to note the columbia bridge existence. and that really you dont necessarily need much of anything.]

approach 1

turns stupid shitty signs to less shitty ones, arrow per lane diag on right, bigass direction sign on left with specific destinations for each lane, below is variant what is more small, though for this i'd like to see the approach 3a sign in action as well
