Instead of directly intersecting US 9, NY 2 meets a series of ramps leading to and from the road while US 9 itself crosses under the circle, allowing for a continuous flow of traffic on US 9.

East of US 9, NY 2 runs southeast through Colonie, serving residential neighborhoods and a short commercialized stretch on its way into the riverside city of Watervliet, where it becomes 19th Street.

[5] The highway initially serves three blocks of homes before entering a linear commercial district at a junction with 12th Avenue.

From here, the road crosses a Canadian Pacific Railway line as it approaches downtown Watervliet,[4] where state maintenance resumes one block west of an intersection with NY 32 (Second Avenue).

The couplet takes the route through the Central Troy Historic District, where NY 2 eastbound heads into a two-block tunnel that carries the highway underneath the campus of Russell Sage College.

The route runs southeastward from the merge, serving another commercial strip in the Eastside section of the city and connecting to the northern terminus of NY 66 (Pawling Avenue).

It loosely parallels the northern edge of Poesten Kill to the Troy city line, where the highway reaches the southern terminus of County Route 141 (CR 141 or South Lake Avenue).

[4] State maintenance of NY 2 resumes as the road heads into the town of Brunswick,[5] where the homes along the highway become less frequent and more scattered.

[4] East of Clums Corners, NY 2 loses the Brunswick Road name as it heads northeast through increasingly rural areas along the Quacken Kill.

The route crosses the western terminus of CR 79 (Blue Factory Road) along this stretch before winding back to the southeast at the Grafton town line.

Past the hamlet, the route changes names to Taconic Trail as it meanders southeastward through rural, mostly wooded sections of Petersburgh.

NY 2 intersects both ends of CR 91 (East Hollow Road) before traversing dense woods in the Berkshire Mountains.

Near Troy, NY 96 bypassed Pawling and Pinewoods avenues to the north on Brunswick Road instead of following the path of Route 42.
