DON”T use you car’s GPS navigation system. PERIOD.
Use a smartphone. It has updated maps and perhaps vectors around traffic.
I use Waze.
Yea, the last time I was stupid enough to use the wonderful smartphone navigation it was running a second or two late
Turn right…back there.
I drive 40,000 plus miles a year, mostly in places I’ve never been. I use a dashboard GPS.
In this case, a paper map would have failed too. A bridge out for years with no signage or barricades is a failure on the part of the county or state.
