Another Danger Zone: The Northeast entrance to Stony Brook University, where 25A and Nicolls road meet. Whether you are coming from Setauket or Port Jeff on 25A or on Sheep Pasture, this place sucks. There are no sidewalks or bike lanes, the cars drive like freaking crazy, and there is a large hill in the campus entrance that comes out of nowhere. The cars turing onto Nicolls here don’t pay any attention, especially those turning right from 25A.
My advice: Skip this university entrance and take the underpass by the hospital.
