Streets, was built in 1934-36 in the Art Moderne style, during the Fiorello LaGuardia administration. The supervising architect was Aymar Embury II, and the landscape architect was Gilmore D. Clarke, among others. It was built on the site of the reservoir which had formerly served the High Bridge Water Tower, and features a swimming pool. Bathhouse The bathhouse is set on an ashlar base above the surrounding street level, while the rest of the structure is made of brick. The building is rectangular: the longer side is on a north-south axis (i.e. parallel to Amsterdam Avenue), while the shorter side is on a west-east axis (i.e. parallel to 173rd Street). Its main entrance is on an elevated, slightly projecting portico at Amsterdam Avenue and 173rd Street. Stone staircases on either side ascend to the portico. The portico itself consists of two brick towers with flagpoles, two concrete piers that carry a concrete architrave, and a bronze sign with the words at the top of the architrave. Just inside the portico, there is a circular turret with a second-story loft, overlooking the first-floor entrance. The north and south wings respectively contain the women's and men's locker rooms and are nearly identical. Both have nine windows separated by eight brick pilasters. The stone capitals of the pilasters line up with the lintels of the windows. Ramps lead from the extreme ends of each wing. The ground slopes down northward, so that the northern wing is at a higher elevation above the ground than the southern wing. The eastern facade is similar to the western facade, except that it contains entrances to both genders' respective locker rooms, as well as a bronze clock hanging from the architrave. A cellar is below the northern wing. Pools The Highbridge Pool contains two rectangular pools: a main pool to the east and a wading pool to the west. The main pool measures wide by long, with the wider dimension extending north-south, and a depth of . The wading pool measures wide by long. A promenade surrounds the pool area on the north, south, and east sides. A set of concrete bleachers is to the north of the pool area. A short brick wall encloses the pool area, and niches along the eastern boundary provide another seating area. Just east of the pool area is a set of stairs that leads to the High Bridge. The water
