However, when US 9 was commissioned in New York in 1927, the US 109 designation had been dropped and was signed instead as US 9E, but only up to Waterford. The segment on the west bank of the Hudson from New Jersey to Waterford was redesignated as US 9W

U.S. Route 9W is a north–south U.S. Highway in the states of New Jersey and New York. It begins on Fletcher Avenue in Fort Lee, New Jersey as it crosses the US 1 & 9, US 46, and the Interstate 95 approaches to the George Washington Bridge, where it heads north up the west...

, with the split routes meeting in Waterford. From there, unsuffixed US 9 began (still along NY 6) and went up to the Canadian border via Rouses Point as planned in 1925.

The former routing of NY 6 between Elizabethtown and Keeseville, bypassed by US 9, became NY 9W at this time. A shorter, more inland alternate route between Albany and Round Lake was designated as NY 9C sometime in the late 1920s. In the 1930 renumbering of state highways in New York, the "E" suffix was dropped from all of US 9E south of East Greenbush—making it part of US 9—while US 9W was truncated southward to end in Albany. At the same time, US 9 was realigned between Albany and Round Lake to use what had been NY 9C. The Waterford–Mechanicville portion of US 9's former routing and the segment of US 9E between East Greenbush and Waterford became part of an extended US 4. The remainder of the old riverside route south of Waterford became part of NY 32 while the Round Lake – Mechanicville segment of old US 9 became part of NY 67.

. In the mid-1960s, the Adirondack Northway was completed in the vicinity of Champlain, supplanting the northernmost 1 miles (1.6 km) of US 9. US 9 initially overlapped with Interstate 87 from exit 43 to the Canadian border; however, it was truncated to end at exit 43—the last interchange before the border—in the 1970s. Part of US 9's former routing to the border was retained as a service road and was designated as NY 971B, an unsigned reference route.

. By 1967, strong resident opposition caused the segment from Peekskill to Beacon to be cancelled. In 1971, the section from Tarrytown to Ossining had also been cancelled due to lack of public support. The only portion that was ever built was the section from Crotonville to Peekskill, and was later named the Croton Expressway. The Croton Expressway opened in 1967 with the US 9 designation.
