New York State Route 9R - Route Description

Route Description

NY 9R begins opposite the entrance to the on-ramp for Interstate 87 (I-87) exit 7 at an intersection with US 9 (Loudon Road) in the Colonie hamlet of Latham, located north of the city of Albany. The junction is also the termination of the off-ramp from the limited-access NY 7 west onto US 9. NY 9R heads east as the four-lane Columbia Street Extension, initially passing through a commercialized area centered around the route's intersections with US 9 and the nearby Old Loudon Road. 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.

Roughly 0.5 miles (0.8 km) west of an intersection with NY 470 on the western edge of the city of Cohoes, the area surrounding the highway changes drastically as the route becomes lined with residential dwellings. The string of homes continue to the junction with NY 470 on the Cohoes city line, where NY 9R turns north onto Baker Avenue, a two-lane street that runs along the border between the town of Colonie and the city of Cohoes. Columbia Street, meanwhile, continues east into downtown Cohoes as NY 470, which begins at NY 9R. Heading north, NY 9R passes through both residential neighborhoods and lightly populated areas. The homes along the Colonie (west) side of the route give way to woods after just 0.3 miles (0.5 km); however, the Cohoes (east) side remains lined with fully populated and developed neighborhoods for another 0.7 miles (1.1 km).

The 1-mile (1.6 km) north–south stretch ends at a junction with Boght Road, known as Manor Avenue within Cohoes. Both highways sit on the northern boundary of what was once the Manor of Rensselaerswyck. NY 9R turns left at this intersection, leaving the city boundary and proceeding westward along Boght Road. The complexion of the roadway is similar to that of the first 0.3 miles of Baker Avenue, as the two-lane road is lined with a steady stream of houses. After 0.75 miles (1.21 km), NY 9R enters a lightly populated hamlet named Boght Corners, where it ends at an intersection with US 9. While the state route ends here, Boght Road continues westward as a town road to Dunsbach Ferry Road, a north–south town highway paralleling I-87 through northern Colonie.
