The poster beat me to this. I actually biked across the road (missed the sign, d'oh!). As I was riding across, I thought, "Shoulder so nice and wide, they'll probably paint in a bike lane." Then in the middle of the bridge I saw another sign, and I high-tailed it before I got caught.
As a motorist, I'm not real comforted that flame-outs are possible here. I'll keep the windows closed.
