Just East of Exit 16 on I-96 there is an "Authorized Vehicles Only" turn around. This perticular turn-around has a bridge immmediatly to the East of it, so it has the mandatory barriers in the median.
These barriers are painted white and black and they sit about 4 foot high during the median.
Guess what kind of car in the area is also painted white and black and sits about 4 foot high?
The speed limit is 70mph, but most drivers readily cruise at 80mph in this open area. Trucks! – be sure to be doing 55mph.
