Re: Caltrans Sharp S-curve on the Bay Bridge claims first life

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I would also like to add that we  should avoid multiple speed zone,
like in this case we have 3 speed zone. 1- Before S curve,50mph. 2- In
S curve, 40mph. 3- Sharp S curve, 35 mph. Its difficult to follow and
half & full asleep man nt gonna see it, so better we avoid it. We CE
have toughest job, we need to make a bridge and then add instruction
fr civilian as a 'civilian' !
