The commercial strip ends at Johnson Road, where the route turns northeastward and narrows to two lanes as it heads into a lightly populated area of Colonie. This section of Columbia Street Extension passes by some commercial buildings; however, most of the development along the highway is residential, with most of the homes located in cul-de-sacs leading away from NY 9R.
