A motorcycle cop is located at the bottom of the bridge in both directions and others are ready to "chase". Most cars move at the psoted 35 or 45 limit; many cars feel that because they can see so far go 50-60mph doing rapid lane changes. It is a speed trap, but seems necessary due to low barriers, construction to prevent horrible accidents with difficult access for EMT. I have been ‘trapped’ on bridge for two hours due to accidents. BEWARE!
