Heading away from the ridge, NY 9D continues on a northerly path through the town of Fishkill, serving the Breakneck Ridge station on the Metro-North Railroad before turning northeastward and diverging from the Metro-North line and the Hudson River. The road soon reaches the southern edge of the city of Beacon, where it becomes Wolcott Avenue and the surroundings transition from rural mountainous scenery to an urban setting. Maintenance of the route also shifts from the New York State Department of Transportation (NYSDOT) to the city. Upon reaching the city center, NY 9D traverses a 90-degree bend to the northwest and becomes the main north-south street through the city. The highway crosses Fishkill Creek ahead of another 90-degree turn, this time to the northeast, giving NY 9D an S-shaped alignment as it travels through downtown Beacon. State maintenance of the road resumes one block east of the northeasterly bend.
