They look like tuna-netting and tear up cars but Michigans cable guardrails save lives.

Plunging temperatures and freezing precipitation wreaked havoc on Michigan roads on January 12 (and many other days). Not one, but two eighteen-wheelers jack-knifed on a busy section of I-96 in Ionia County but it was the cable guardrails that saved lives. The posts were toppled but the steel ropes held and the trucks were prevented from crossing the median into oncoming traffic.
