Worst Traffic Jams in History! Where R U Going???

My only thought is, around where I live and the place I need to get to ,has several big bridges, now early on these might be clear or slow going. Later on for travel, I am sure they will be monitored by militias or raiders either way very dangerous. May have to trade or give something up a value to get past.

I have only one main way out if all of the bridges are slammed, other than going on foot. Still, you have to at least have some thought that you may need to hoof it vs. drive, if it comes down to it. I'm hoping that at least ONE of the four bridges are available though. Would be a LONG walk.
