Question: The Mechanicville Bridgecarries New York State Route 67 across the Hudson River in New York connecting Mechanicville with Hemstreet Park in which town in Rensselaer County, New York, United States?
Context: New York State Route 9G (NY 9G) is a state highway in the Hudson Valley of New York in the United States.  It runs north from U.S. Route 9 (US 9) at Poughkeepsie, starting out as Violet Avenue, then follows the Hudson River mostly along the eastern side of the US 9 to Rhinebeck, where the two routes cross just north of the village.  From this point onward, NY 9G runs on the western side of US 9, closer to the Hudson River, to Hudson.  It ends at another junction with US 9 in the city.  NY 9G initially extended from Rhinebeck to Hudson when it was assigned as part of the 1930 renumbering of state highways in New York.  It was extended to its current length in the late 1930s, supplanting New York State Route 9F, an alternate route of US 9 between Poughkeepsie and Rhinebeck. Schaghticoke is a town in Rensselaer County, New York, United States.  The population was 7,679 at the 2010 census.  It was named for the Schaghticoke, a Native American tribe formed in the seventeenth century from an amalgamation of remnant peoples of eastern New York and New England.  The tribe has one of the oldest reservations in the United States, located in what is now Litchfield County, Connecticut.  It has been recognized by the state of Connecticut but has not yet achieved federal recognition. The Mechanicville Bridge (also known as the Hemstreet Park Bridge) carries New York State Route 67 across the Hudson River in New York connecting Mechanicville with Hemstreet Park in the Town of Schaghticoke.  The bridge was built in 1950 as a replacement for a structure privately built as a toll bridge in 1888, and is referred to by some as the Champlain Canal Bridge. New York State Route 67 (NY 67) is an east–west state highway in eastern New York in the United States.  The western terminus of the route is at an intersection with NY 5 in the town of St. Johnsville.  Its eastern terminus is at the Vermont state line in Hoosick, where it continues eastward as Vermont Route 67 (VT 67). New York State Route 66 (NY 66) is a state highway in the Capital District of New York in the United States.  The route begins at an intersection with NY 23B in the Columbia County city of Hudson and ends at a junction with NY 2 in the Rensselaer County city of Troy.  While both Hudson and Troy are located on the Hudson River, NY 66 follows a more inland routing between the two locations to serve several rural villages and hamlets, including Chatham and Sand Lake.  NY 66 overlaps with U.S. Route 20 (US 20) and NY 43, two regionally important east–west highways, in Nassau and Sand Lake, respectively. Stillwater Bridge is a truss bridge in the Capital District of New York in the United States.  It carries Stillwater Bridge Road (New York State Route 915C or NY 915C, an unsigned reference route) across the Hudson River from the village of Stillwater in Saratoga County to the town of Schaghticoke in Rensselaer County.  The bridge is two lanes wide and has a sidewalk only along the south side of the road. North Hoosick is a hamlet in Rensselaer County, New York, United States.  The community is located along the Walloomsac River at the intersection of New York State Route 22 and New York State Route 67, 1.9 mi north of Hoosick Falls.  North Hoosick has a post office with ZIP code 12133. New York State Route 9J (NY 9J) is a north–south state highway in the Hudson Valley region of New York in the United States.  It begins at an intersection with US 9 in the Columbia County town of Stockport and extends for 22.35 mi to an interchange with US 9 and US 20 in the Rensselaer County city of Rensselaer.  The route parallels the Hudson River for its entire length, and several parts of the highway run directly alongside the river.  NY 9J was assigned to its current alignment as part of the 1930 renumbering of state highways in New York. The Maiden Lane Bridge was a railroad bridge across the Hudson River between the city of Albany and Rensselaer County, New York.  It was designed by Kellogg, Clark & Co., and was one of the largest bridges they designed.  The bridge was owned and built by the Hudson River Bridge Company, which was owned jointly by the New York Central and Hudson River Railroad Company which owned 3/4, and the Boston and Albany Railroad Company which owned 1/4.  The Maiden Lane Bridge was often referred to as the "South Bridge", while the Livingston Avenue Bridge was referred to as the "North Bridge".  The Livingston Ave. Bridge was used for freight (and through-traffic passenger trains) while passenger trains used the Maiden Lane Bridge for access to Union Station, which was completed less than 10 months later.  The state of New York authorized construction on May 10, 1869, construction began in May 1870, and the first train crossed on December 28, 1871.  The bridge consisted of four 185.5 ft long fixed spans, one 274 ft long draw span, seven 73 ft long spans over the Albany Basin, one 110 ft long span over Quay Street, and one 63 ft long span over Maiden Lane.  All the spans except the one over Maiden Lane were double tracked, through, and pin connected; the span over Maiden Lane was also double tracked, but was a deck and plate girder span.  A reconstruction of the bridge, except for the draw span, was done in 1899 by Pencoyd Bridge Company and finished by January 3, 1900.  The bridge lasted until the 1960s, when the Albany-Rensselaer Amtrak Station was built on the east side of the Hudson in the city of Rensselaer and Interstate 787 was built along the west side in Albany, thereby eliminating the need of the bridge. New York State Route 154 (NY 154) was a state highway in Rensselaer County, New York, in the United States.  It began at an intersection with U.S. Route 4 (US 4) in the city of Troy and ended at then-County Route 77 (CR 77, now NY 351) in the hamlet of Poestenkill.  Along the way, it intersected NY 66 and NY 355.  The route was assigned in the early 1930s and eliminated in 1980 as part of a highway maintenance swap between the state of New York and Rensselaer County.  The portion of the highway between the Troy city line and NY 355 became County Route 130 while the part connecting NY 355 to Poestenkill became an extension of NY 355.
