 At Fishkill, the road passes the historic Van Wyck Homestead Museum and it becomes a six-lane divided strip until reaching the Poughkeepsie city limit.It then narrows to a four-lane divided strip which lasts until it intersects St. Andrews Rd, just north of the Hyde Park/Poughkeepsie town line where it returns to two-lane status as it goes through Hyde Park and past its historic sites.At Red Hook US 9 veers inland again, becoming a two-lane country road through Columbia County save for the outskirts of Hudson.
