NY 329 originally extended as far west as the hamlet of Townsend; however, it was cut back to its current length in the 1960s.

NY 329 progresses eastward, passing through a mix of forestry and residential homes, intersecting with Willow Drive, a local cul-de-sac, crossing a local railroad line and entering Watkins Glen State Park.

There, the highway becomes further surrounded by residences, soon turning to the northeast, leaving the residential area for forestry and fields.

The route, a mere 0.39 miles (0.63 km) long, comes to an end at the southern entrance to the park.

[2][11] NY 329 was truncated to its current western terminus at Meads Hill Road in the 1960s.

During the 1952 race, a car briefly entered the crowd that had lined up along the course, killing one person and injuring several others.

[15] The entirety of the old Grand Prix road course was added to the National Register of Historic Places on December 4, 2002.
