At an intersection with Gurley Avenue, NY 142 continues along Northern Drive and enters the local greens on Oil Mill Hill.

A short distance later, NY 142 re-enters downtown Troy passing through the residential and commercial districts.

At the intersection with 125th Street, the designation turns off of Northern Drive and heads westward into the Lansingburgh district.

[6] NY 40 was realigned by 1932 to follow Leversee Road and Oakwood Avenue through the eastern outskirts of Troy.
