Going-to-the-Sun Road is a scenic mountain road in the Rocky Mountains of the western United States, in Glacier National Park in Montana. The Sun Road, as it is sometimes abbreviated in National Park Service documents, is the only road that traverses the park, crossing the Continental Divide through Logan Pass at an elevation of 6,646 feet (2,026 m), which is the highest point on the road. Construction began in 1921 and was completed in 1932 with formal dedication in the following summer on July 15, 1933. Prior to the construction of the road, visitors would need to spend several days traveling through the central part of the park, an area which can now be traversed within a few hours, excluding any stops for sightseeing or construction.
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 Although the aqueduct was largely superseded by the New Croton Aqueduct, which was built in 1890, the Old Croton Aqueduct remained in service until 1955.
The Blackstone Canal was a waterway linking Worcester, Massachusetts, to Providence, Rhode Island through the Blackstone Valley via a series of locks and canals during the early 19th century.

It was ultimately replaced by the Providence and Worcester Railroad, which completed a parallel line using much of the canal right-of-way in 1847, the canal shut down in 1848. Several segments of the canal are preserved.

Northwestern Consolidated Milling Company was an American flour milling company that operated about one-quarter of the mills in Minneapolis, Minnesota, when the city was the flour milling capital of the world. Formed as a business entity, Northwestern produced flour for the half-century between 1891 and 1953, when its A Mill was converted to storage and light manufacturing. At its founding, Northwestern was the city's and the world's second-largest flour milling company after Pillsbury, with what is today General Mills a close third.
