Thus, the 0.34-mile (0.55 km) segment of New Turnpike Road between the county line and NY 10 has no reference markers.

After passing an unusual flashing traffic light at Guy Park Manor, a four-lane highway begins parallel to Main Street.

NY 67 enjoys a wider route, enabling faster driving and more gentle curves, passing south of the village of Galway.

After the final roundabout, NY 67 turns south, concurrent with US 9 for 1.5 miles (2.4 km), just north of the village of Round Lake.

Here, the route heads eastward, taking a winding path toward Mechanicville and the Hudson River.

Turning left and overlapping, the routes enter Schaghticoke upon crossing the Hoosic River.

Turning right, running concurrent for 0.6 miles (1.0 km), the paired routes re-enter Rensselaer County.

Passing through farmland, NY 67 ends at the Vermont state line, continuing as VT 67.

[10] In the 1930 renumbering of state highways in New York, US 9 was realigned onto its modern alignment between Albany and Round Lake.

[11] On April 1, 1980, ownership and maintenance of NY 67 between the access road to lock 4 of the Champlain Canal and NY 40 was transferred from the state of New York to Rensselaer County as part of a highway maintenance swap between the two levels of government.

[12] NY 67 was realigned to follow the new state highway between Mechanicville and Schaghticoke[13][14] while the county-maintained portion of its former alignment became CR 125.

[13][14] The 0.34-mile (0.55 km) section of New Turnpike Road between the Fulton County line and NY 10 was not transferred to the state and is still maintained by the town of Ephratah for several years.
