Yukon–Charley Rivers National Preserve is a United States national preserve located in east central Alaska along the border with Canada. Managed by the National Park Service, the preserve encompasses 130 miles (208 km) of the 1,800-mile (3,000 km) Yukon River and the entire Charley River basin. The preserve protects the undeveloped Charley River and a significant portion of the upper Yukon. The interior Alaskan region experiences extremes of weather, with temperatures that can vary from −50 °F (−46 °C) in winter to 97 °F (36 °C) in summertime. The Yukon provided a means of access to the region, which is entirely roadless, during the late 19th century and early 20th centuries. Gold rushes in Alaska brought prospectors, who operated gold dredges to recover significant quantities of placer gold from area creeks. Today the preserve includes part of the route of the annual Yukon Quest dogsled race, which runs every February. During the summer float trips are popular on the Yukon and Charley Rivers.
The Croton Aqueduct or Old Croton Aqueduct was a large and complex water distribution system constructed for New York City between 1837 and 1842. The great aqueducts, which were among the first in the United States, carried water by gravity 41 miles (66 km) from the Croton River in Westchester County to reservoirs in Manhattan. It was built because local water resources had become polluted and inadequate for the growing population of the city. Although the aqueduct was largely superseded by the New Croton Aqueduct, which was built in 1890, the Old Croton Aqueduct remained in service until 1955.

Five of them were built in 1928, with the remainder built between 1921 and 1933. The bridges feature a concrete structure faced with local stone, in an elliptical or three-centred arch configuration.
