Do you see a "Road Closed" as a stop/re-route signal or a "pause then go suggestion"? Unless I am running late and in a "cut my losses" mode I can't help but react with a "maybe for most people, but I am more likely than not going to be able to find a way through" reaction. I'd guess my success rate is at least 50%, either just weaving around obstructions (potholes, half jack hammered road, or maybe a shallow creek bridge out/under construction (happens a fair amount in MO). Sometimes it's truly impassable so I turn around. I know it's shallow but I feel badass when I do make it through! I do not go when I see workers active on site. Do you go or turn when you see the sign?
