I was driving to get my friend after work one late night and I was on the west end bridge and I took the on ramp to 279. There was a black car, abandoned, parked going the wrong way half way down the onramp. Of course it was winter and snowing so I didn't see the car until too late. I swerved, hit a patch of black ice and ended up hitting the jersey barrier a bit further down. They had to be driving the wrong way on 279 for quite a while before they got to the onramp.
