 Two miles (3.2 km) to the east, Signs appear for Saw Mill Road, exit 1 on Connecticut's stretch of I-84, and its ramps leave the highway just a hundred feet (30 m) before the state line.The route of what became I-84 through New York state began in the late 1940s, when the then-New York State Department of Public Works (now NYSDOT) was planning Gov.Thomas Dewey's proposed Thruway system.
