Wikipedia:WikiProject U.S. Roads/New York/Resources/Maintenance swaps

The following is a list of most—if not all—of the highways that the state of New York has transferred ownership and maintenance of to a county or a town, city, or village (listed in the tables below as "local") or highways that a county, town, city, or village has transferred ownership and maintenance of to the state of New York since 1979. These transfers of highway ownership and maintenance (also known as "maintenance swaps") were derived from the text of the New York State Highway Law, specifically §341. NYSDOT quadrangles and NYSDOT inventories were also used to find many of the state highway numbers listed below. See this user-maintained New York reference page for a reference to use in articles.

Note that there are a large number of undated highway swaps in the law text. These undated swaps are ones that took place at a time determined by other factors instead of at a set date. Many of these never took effect—usually because the "trigger" highway was never built—but some did.

The columns below indicate the following:
 * Date: the date the swap took effect
 * County: the county that the state swapped highways with
 * Route: the relevant route for this entry; note that the given route may or may not have existed at the time of the swap
 * Description of road transferred: self-explanatory. Designations listed in parentheses after another designation (such as "NY 353 (SH 48015)" or "NY 19 (CR 232)") are the internal designations that the highway had on a state or county level, respectively, when the swap occurred.
 * From: the level of government that owned/maintained the highway prior to the swap
 * To: the level of government that owned/maintained the highway after the swap
 * Designation: the primary post-swap designation of the highway
 * SH #: for state numbered highways only. This column lists the route's legislative state highway number (9xxx) if it became state-maintained or the route's concurrent county route designation (CR x) if it became county-maintained.
 * Notes: mostly historical notes about the transferred highway

If you have questions about this list or a given entry, feel free to post on WT:NYSR.

A yellow background indicates that the swap is still in current law. A red background indicates that it was repealed without happening; a blue background indicates that it was repealed after being carried out (perhaps by a different law).

Nassau County (1924)
[http://babel.hathitrust.org/cgi/pt?id=uc1.b4378092&seq=775 1923 ch. 479] authorized (but did not direct) an exchange. It did not happen as described, and [http://babel.hathitrust.org/cgi/pt?id=uc1.b4378093&seq=572 1924 ch. 291] authorized a similar exchange that was carried through.

1928 abandonment law
[http://babel.hathitrust.org/cgi/pt?id=uc1.a0001859750&seq=1351 1928 ch. 597] authorized, but did not direct, the state to abandon a large number of minor segments to the counties. Some were transferred very quickly, some were later required by other laws, and some are still state highways.

Nassau and Suffolk Counties (1931)
[http://babel.hathitrust.org/cgi/pt?id=uc1.b4378099&seq=924 1931 ch. 391] authorized (but did not direct) an exchange. It seems to have been carried through.

Monroe County (2007)
The text regarding this swap in Highway Law §341 has no date; however, the full text of the act that added this swap to §341 (S4856, 2007; use the legislature's bill search to find it) indicates that the act "[took] effect on the ninetieth day after it [became] a law" (S4856, 2007). It was signed into law on August 28, 2007; 90 days after that date was November 26, 2007. Thus, the entirety of the swap below officially took place on the latter date.

Chenango County (1984)
The swap below was conditional on the construction of a highway "beginning at a point on the Cortland-Chenango county line, thence running generally northeasterly on or in the vicinity of county highway forty-two to a point on state highway eight hundred seven [NY 23] in or near the hamlet of Scott Corners, as determined by the commissioner" (§341-8-2). This highway became the portion of NY 23 from the county line northeast to Scott Corners in Pharsalia (SH 82-10 and SH 83-4). Based on the date given for the removal of NY 319 in the NYSDOT route log and based on contemporary maps showing when NY 23 was realigned, the swap took effect in July 1984. Incidentally, CR 42, which was essentially replaced by NY 23, was reassigned by Chenango County to old NY 23 (see below).

Erie County (1980s)
The swap below was conditional on the construction of the "Southern expressway, beginning at state highway one thousand three hundred thirty-three [NY 39] near the village of Springville, thence running generally northerly to the New York state thruway, Erie section, near the city of Lackawanna" (§341-14-4). To this day, this is the only section of the expressway that has been built. The date that this swap went into effect is unclear: the last segment of the Southern Expressway was completed in the early 1980s; however, NYSDOT gives a 1988 removal date for NY 356 and NY 356 is marked on the 1985 Rand McNally map of New York. Thus, "1980s" is about as accurate as we can get for now.
