New York State Route 73
state highway in Essex County, New York, US
New York State Route 73 (NY 73) is a 27.55-mile-long (44.34 km) state highway located entirely within Essex County, New York, in the United States. The highway begins at an intersection with NY 86 in the village of Lake Placid and ends at a junction with U.S. Route 9 (US 9) north of the hamlet of Underwood in the extreme southwestern corner of the town of Elizabethtown. NY 73 meanders through a mountainous region of Adirondack Park and passes by several named peaks, including Porter Mountain and Lower Wolfjaw Mountain. Along the way, the route has a short concurrency with NY 9N in the town of Keene.
In the early 19th century, Lake Placid and Keene were connected by the North West Bay Road, an east–west highway linking Hopkinton to Westport. The highway was initially a crude, impassable road; however, it was significantly improved by the state of New York in the mid-1810s. A highway linking Keene to Underwood was constructed by 1846; at Underwood, the road connected to a stagecoach road that went from Albany to the Canada–US border. The latter road became the basis for most of modern US 9.
NY 73 was assigned as part of the 1930 renumbering of state highways in New York from NY 28N in Tahawus to NY 22 in Ticonderoga. The portion of the route from Tahawus to North Hudson followed the Blue Ridge Road; from North Hudson to Schroon, NY 73 overlapped US 9.

Why this record matters
The subject matters to the places & architecture register because the source frames it as state highway in Essex County, New York, US. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Oct 20, 2025. The linked authority identifier is Q452121. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1846 and 1930.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
