Emergency crossover lanes are actually quite common, but rarely used (and due to this, not even mapped). Such as this (not US, but first one that came to my mind): https://www.openstreetmap.org/way/353606400#map=17/50.03606/...

You arrive from the northwesternmost link, the outer lanes south are blocked, so police opens up the service link (which is normally physically closed by a barrier and correctly mapped as "no access") and routes the traffic through it, into the inner lanes.

Now you also have an indecisive truck sitting in the mess, waiting for a human to intervene.
