My dad told me late this afternoon that the US 41 twin bridges south of Evansville were closed for at least an hour this afternoon after a barge hit one of the piers. In the years I lived in Evansville, I don't recall that ever happening. I have attached the link to a newspaper story about it.

That could be major..........but could make a I-69 bridge more in the spotlight.
They have barge strikes down toward Paducah all the time -- the US 51, 45 and I-24 bridges have it happen more often than you'd think.
