[6] From Feura Bush Road, NY 335 heads northward as a two-lane street named Elsmere Avenue, passing several housing tracts in an otherwise open area of the town.

After a half-mile (0.8 km), the route meets the Delmar Bypass, a four-lane divided highway carrying NY 32 through Bethlehem.

[2][3] In 1959, the state of New York developed plans for the Delmar Bypass, which would intersect NY 335 a short distance north of Feura Bush Road.

[10] The Bethlehem Central Board of Education had called for a grade-separated interchange between the highway and NY 335 to ensure the safety of school buses on the latter road, a major bus route;[11] however, the junction was ultimately built as an at-grade intersection.

In mid-January 1964, the Bethlehem Town Board pushed the state to add traffic lights to every intersection in the wake of several accidents and near-misses at the crossings.
