The bike bounced off its left side when it decided it couldn't fly!! Right side of bike no damage. And most damage done to me was on left side. 12 broken ribs and broken shoulder. Right side just broken clavical and busted head. At least bleeding on brain was on right side. Low side High side??? I was going in a straight line?? The bridge did have that metal grid filled with blacktop with the grid sticking out of the blacktop. I know this stuff can get slick.Slick surface start it sliding and it just continued?? I DON"T KNOW!!!!:bang head:
