re: Interstate Cable Barriers

The middle is often a low spot, so there’s a “distinct possibility” of an errant vehicle vaulting over the cables. The soils are often poor, said Kent Barnard of MnDOT.

If one direction of the freeway is higher than the other, that side of the median gets the cable. Engineers also review which side of the road has had more drivers zooming into the median. They’ll place the cable on the opposite side to give the veering drivers more room to recover on their own
