This is a new trap now that 93 south is underground. Reduce speed to 40 MPH as you cross the Leonard P. Zakum Bridge. State Troopers sit on the far left side of the tunnel, usually 5 or more at a time using up to two guns flagging speeders over as they come down hill to the underground portion. This trap comes out after 10:30 at night on weeknights, and many people get pulled over. I cannot stress it strong enough watch your speed in the downtown section of 93 south.
