through downstate New York to the Pennsylvania state line; however, it was several years before NY 52 as a whole was improved and paved. At its west end, NY 52 connected with US 106, which had been designated in 1926 and ended at the Delaware River on the Pennsylvania state line. US 106 was never extended into New York, and is now PA 652 near the border. To the east of East Fishkill, the newly designated NY 52 used the old alignment of 1920s Route 39 from East Fishkill to West Patterson, where 52 continued along previously unnumbered roads south to Carmel, then east to NY 22 at Sears Corners (northeast of Brewster) over modern NY 311, US 6, and NY 312, as well as its modern alignment from Lake Carmel to Carmel. At the time, modern NY 52 from Stormville to Ludingtonville (northwest of Lake Carmel) was designated as part of NY 216. NY 52 and NY 216 mostly swapped alignments in the area ; NY 52 was rerouted onto its modern alignment between Stormville and Lake Carmel, utilizing the portion of NY 216 from Stormville and Ludingtonville as well as a new roadway between Ludingtonville and Lake Carmel while NY 216 was relocated to the old Route 39 alignment (Stormville–Poughquag–West Patterson). The original NY 52 segment from West Patterson to Lake Carmel was assigned as an extension of NY 311. NY 52 was also truncated to its present terminus in Carmel at this time. Realignments and detours The only major change to NY 52's routing since then came with the opening of the Newburgh–Beacon Bridge in 1963. Prior to then, NY 52 had crossed the Hudson River on the Newburgh–Beacon Ferry, approaching from the west on Dupont Avenue and Broadway (overlapping NY 17K on Broadway) and from the east on Fishkill Avenue and Wolcott Avenue (now mostly NY 52 Business). Natural disasters and construction have forced temporary closures and re-routings in some areas. At the end of 2002, a rockslide along the stretch climbing the Shawangunks east of Ellenville buried an 85-foot (25 m) section of the road with an estimated 1,000 cubic yards (800 m³) of rock and dirt. The state Department of Transportation closed the road temporarily. Automobile traffic was detoured via several local roads; trucks had to make a lengthy side trip via Route 17 During the 2003–2005 construction of the new bridge over the
