Question: The Tower Hotel is located on the east side of of a bridge that is now owned nad maintained by who?

<P0-S0> Tower Bridge is a combined bascule and suspension bridge in London built between 1886 and 1894. <P0-S1>  The bridge crosses the River Thames close to the Tower of London and has become an iconic symbol of London, resulting in it sometimes being confused with London Bridge, situated some 0.5 mi upstream. <P0-S2>  Tower Bridge is one of five London bridges now owned and maintained by the Bridge House Estates, a charitable trust overseen by the City of London Corporation. <P0-S3>  It is the only one of the Trust's bridges not to connect the City of London directly to the Southwark bank, as its northern landfall is in Tower Hamlets. <SEP> <P1-S0> The Maiden Lane Bridge was a railroad bridge across the Hudson River between the city of Albany and Rensselaer County, New York. <P1-S1>  It was designed by Kellogg, Clark & Co., and was one of the largest bridges they designed. <P1-S2>  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. <P1-S3>  The Maiden Lane Bridge was often referred to as the "South Bridge", while the Livingston Avenue Bridge was referred to as the "North Bridge". <P1-S4>  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. <P1-S5>  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. <P1-S6>  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. <P1-S7>  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. <P1-S8>  A reconstruction of the bridge, except for the draw span, was done in 1899 by Pencoyd Bridge Company and finished by January 3, 1900. <P1-S9>  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. <SEP> <P2-S0> The Tower Hotel, is a large hotel situated on the north bank of the River Thames, on the east side of Tower Bridge, in London. <SEP> <P3-S0> Lenox Hill Neighborhood House (the “Neighborhood House”) is a multi-service community-based organization that serves people in need on the East Side of Manhattan and on Roosevelt Island. <P3-S1>  Founded in 1894 as a free kindergarten for the children of indigent immigrants and as one of the first settlement houses in the nation, Lenox Hill Neighborhood House is the oldest and largest provider of social, legal and educational services on Manhattan’s Upper East Side. <P3-S2>  Each year, they assist thousands of individuals and families who range in age from 3 to 103, represent dozens of races, ethnicities and countries of origin and "live, work, go to school or access services" on the East Side from 14th Street to 143rd Street and on Roosevelt Island. <P3-S3>  Their clients include indigent families and the working poor who live in the East Side's housing projects and tenements or who travel to the Upper East Side to work in low-wage jobs such as cashiers, housekeepers, nannies and laborers; 10,000 seniors; and hundreds of mentally ill homeless and formerly homeless adults. <P3-S4>  They have five locations between 54th and 102nd Streets, offer programs at dozens of East Side locations; their headquarters is located on East 70th Street.
