High Quality Content by WIKIPEDIA articles! New York State Route 408 (NY 408) is a 15.95-mile (25.67 km) state highway located entirely within Livingston County, New York, in the United States. It runs north–south from an intersection with NY 70 near the hamlet of Dalton in the town of Nunda to a junction with NY 63 in the town of Groveland near NY 408`s exit with Interstate 390 (I-390). Most of NY 408 is a two-lane rural highway that passes through lightly developed areas; however, the last two miles (3 km) of the highway, where it runs in a due east–west direction, are heavily trafficked as NY 408 becomes a key connector road in both directions.
