When I was still up in Crapids i remember a US10 bridge over railroad tracks that was between the Foley and Hanson exits being a gauntlet of black ice. Always saw people spinning out and hitting the walls or going into the ditch there. Especially westbound.
I think I know that road….and yeah. Frankly, all those bridges up there are *ed. Maybe it’s lack of familiarity, I dunno, but man, what a cluster.
I think part of it was that it was where cars would stack up bumper-to-bumper during the afternoon rush hour. The exhaust probably settled and froze to the pavement there.
