4) Bridges, tunnels, and bottlenecks
I imagine that, in the scenario I presented earlier about being trapped in a traffic jam on a highway as a herd of zombies swarm over you, some of you might have said “Why not drive into the woods or hills or whatever is next to the highway?“.
To that, I say: “What if you can’t?”
Depending on where you are, it won’t be too hard to find portions of roads (Whether they’re highways or not) that are on bridges, in tunnels, or some other kind of bottleneck that makes “getting out” much more difficult than it might otherwise be on an ordinary highway. If you’re on a bridge over a river, a ravine, or some twenty-thirty feet above street level, or in the middle of a tunnel, there is no “next to” the highway, it’s either a wall or…certain death.
How to avoid it?
Once again, this is where having a map comes in handy. Maps will tell you, at the very least, where bridges and tunnels will be, but, what they can also tell you, is where another road, maybe one that isn’t a potential deathtrap, that will get you where you want to go, is. This is important because, those roads (Should they exist), will probably be your best bet to avoid the roadblocks and potential ambush scenarios that bridges, tunnels, toll booths, etc. can create. Sometimes, the only way to avoid a dangerous obstacle…is to go around it.
