Question: The South Mall Arterial is a 0.52 mi expressway in Albany, New York, it begins at an intersection with Swan Street and runs eastward under the Empire State Plaza to the west end of the Dunn Memorial Bridge, officially known as the Private Parker F. Dunn Memorial Bridge, carries US 9 and US 20 across the Hudson River between Albany, New York and Rensselaer, New York, in which country?
Context: 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 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. U.S. Route 9W (US 9W) is a north–south U.S. Highway in the states of New Jersey and New York.  It begins in Fort Lee, New Jersey, as Fletcher Avenue crosses the US 1–9, US 46, and the Interstate 95 (I-95) approaches to the George Washington Bridge, and heads north up the west side of the Hudson River to US 9 in Albany, New York.  As its "W" suffix indicates, US 9W is a westerly alternate route of US 9 between the two locations.  US 9W directly serves three cities—Newburgh, Kingston, and Albany—and enters the vicinity of several others.  As the route heads north, it connects to several highways of regional importance, including I-84, US 209, New York State Route 23 (NY 23), and US 20.  Much of US 9W parallels the New York State Thruway and NY 32; additionally, the latter overlaps with US 9W in four different locations. The South Mall Arterial is a 0.52 mi expressway in Albany, New York, in the United States.  It begins at an intersection with Swan Street and runs eastward under the Empire State Plaza to the west end of the Dunn Memorial Bridge, where the highway ends at an interchange between Interstate 787 (I-787), U.S. Route 9 (US 9), and US 20.  The road is maintained by the New York State Department of Transportation (NYSDOT) as New York State Route 913V (NY 913V), an unsigned reference route. The War Mothers Memorial Bridge is a box girder bridge that carries US 60 and KY 420 across the Kentucky River in Frankfort, Kentucky.  The bridge carries approximately 12,900 cars per day as of 2009.  The bridge was built in 1938.  At some point, US 60 was shifted from the Singing Bridge just downstream to the War Mothers Memorial Bridge.  This bridge connects Frankfort to the Kentucky State Capitol. The Castleton Bridge is a cantilever truss bridge over the Hudson River, connecting Coeymans, Albany County with Schodack, Rensselaer County in New York.  It carries the Berkshire Connector of the New York State Thruway.  This bridge is also sometimes called the Castleton-on-Hudson Bridge and is situated in close proximity to the Alfred H. Smith Memorial Bridge, which is used by rail traffic. 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. U.S. Route 9 (US 9) is a U.S. highway in the northeast United States, running from Laurel, Delaware north to Champlain, New York.  In New Jersey, the route runs 166.80 mi from the Cape May–Lewes Ferry terminal in North Cape May, Cape May County, where the ferry carries US 9 across the Delaware Bay to Lewes, Delaware, north to the George Washington Bridge in Fort Lee, Bergen County, where the route along with Interstate 95 (I-95) and US 1 continue into New York City.  US 9 is the longest U.S. highway in the state.  From North Cape May north to Toms River in Ocean County, US 9 is mostly a two-lane undivided road that closely parallels the Garden State Parkway and runs near the Jersey Shore.  Along this stretch, it passes through the communities of Rio Grande, Cape May Court House, Somers Point, Pleasantville, Absecon, Tuckerton, Manahawkin, and Beachwood.  In the Toms River area, US 9 runs along the Garden State Parkway for a short distance before heading northwest away from it and the Jersey Shore into Lakewood Township.  Upon entering Monmouth County, the route transitions into a multilane suburban divided highway and continues through Howell Township, Freehold Township, Manalapan Township, Marlboro Township, Old Bridge Township, Sayreville, and South Amboy.  In Woodbridge Township, US 9 merges with US 1 and the two routes continue through northern New Jersey as US 1/9 to the George Washington Bridge. The Dunn Memorial Bridge, officially known as the Private Parker F. Dunn Memorial Bridge, carries US 9 and US 20 across the Hudson River between Albany, New York and Rensselaer, New York.  Completed in 1969 to replace an earlier span bearing the same name, the highway bridge has a steel girder design.  It is the southernmost toll-free road crossing of the Hudson.  It is named for Parker F. Dunn, an Albany native who was posthumously awarded the Medal of Honor for his service in World War I. The Governor Nelson A. Rockefeller Empire State Plaza (known commonly as the Empire State Plaza, and less formally as the South Mall) is a complex of several state government buildings in downtown Albany, New York.
