New York State Route 420 - Route Description

Route Description

NY 420 begins at an intersection with US 11 in the town of Stockholm. The route heads north as a two-lane highway through forested areas and across both branches of the St. Regis River to the hamlet of Winthrop, the first area of significant development along the highway. Here, the two branches of the St. Regis River converge and NY 420 meets NY 11C. NY 420 turns northeastward, overlapping NY 11C for two blocks before splitting from it in the center of Winthrop.

The route heads northwest from Winthrop, passing through heavily forested areas of St. Lawrence County. As NY 420 passes out of Stockholm and into Norfolk, the forests surrounding the highway begin to taper off and give way to small pockets of residences and cultivated fields. The amount of homes along the route begin to increase upon intersecting Plum Hill Road, at which point NY 420 becomes lined with residences for much of its run through north Norfolk. However, the string of homes ends near the northern town line, and the highway becomes flanked by forests once more as it curves northward and enters the town of Massena.

In Massena, the forests along NY 420 subside slightly as it passes by industrial warehouses and residences. The route curves back to the northwest as it enters the village of Massena. Just past the village line, NY 420 crosses the St. Lawrence Subdivision, a railroad line owned by CSX Transportation. The highway continues on, curving northward to cross the Raquette River. It curves back to the northwest on the northern riverbank and passes by a mixture of homes and commercial establishments before intersecting NY 37 south of the village center. NY 420 ends here; however, the road continues north into the heart of the village as Main Street.
