Cabbage hill is something like 6 miles up a 6% grade and about the same down with switch back turns. I think there is 2 truck escape ramps on the down grade. Never seen them being used, but seen truck tracks going way up them. For those who do not know DOT places thick gravel on a steep uphill off ramp.
The idea is a truck that lost it's brakes can get off the freeway and not kill someone. They go up the ramp and can finally come to a stop. Some slide back down a ways. They have big tow anchors buried into the ground. A tow truck gets them back on the road.
