Traveling east on Route 78, as you approach and also leave the toll barrier, Waze announces (assuming you are heading to Manhattan) “Stay to the left for exit for 14 A, 14B, 14C” (or something along those lines). The sign as you exit the barrier reads “Holland Tunnel”, no mention of the exit number.
