U.S. Route 209
U.S. Numbered Highway in Pennsylvania and New York in the United States

U.S. Route 209 (US 209) is a 211.74-mile (340.76 km) long U.S. Highway in the states of Pennsylvania and New York. Although the route is a spur of US 9, US 209 never intersects US 9, coming within five miles of the route and making the short connection via New York State Route 199 (NY 199). The southern terminus of the route is at Pennsylvania Route 147 (PA 147) in Millersburg, Pennsylvania. The northern terminus is at US 9W north of Kingston in Ulster, New York, where the road continues east as NY 199.
In Pennsylvania, the highway travels through the length of the Delaware Water Gap National Recreation Area, along the southern part of the Poconos in Monroe and Carbon counties through Jim Thorpe and along parts of the defunct historic Lehigh Canal and Lehigh Valley Railroad then over the divide near Nesquehoning into the Schuylkill Valley along Panther Creek. For part of its route in New York, US 209 runs alongside the defunct Delaware and Hudson Canal, which ran from Port Jervis to Kingston, in each case, following the old land road connections connecting the anthracite coal fields of Northeastern Pennsylvania with the industries and heating customers in New York City.
US 209 is one of the original highways in the 1926 U.S. Highway System plan. The route was initially an intrastate highway contained entirely within Pennsylvania. It began at an intersection with US 11 (now US 22 / US 322) in Clarks Ferry (east of Duncannon) and ended at US 6 in Milford. US 209 was extended northward to US 9W in Kingston, New York, in April 1935 and truncated to Millersburg, Pennsylvania, by 1938.
This brief starts where responsible research should: with the source description of “U.S. Route 209” as u.S. Numbered Highway in Pennsylvania and New York in the United States. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as u.S. Numbered Highway in Pennsylvania and New York in the United States. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jun 20, 2026. The linked authority identifier is Q935294. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1926, 1935 and 1938.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. 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.
