Broad Canal is a short canal in East Cambridge, Massachusetts, previously larger and part of the now-vanished canal system that made Cambridge an active seaport.

Canal man-made channel for water

Canals, or navigations, are human-made channels, or artificial waterways, for water conveyance, or to service water transport vehicles.

The canal began in 1806 when Henry Hill, Rufus Davenport, and others laid out a canal system in the land and tidal flats along the Charles River. Broad Canal was dug before 1810, and 80 feet (24 m) wide from the low-water mark to Portland Street. In 1874 the lower part of the canal, between First and Third Streets, was 100 feet (30 m) wide. Connecting canals ran through much of today's East Cambridge.

Charles River river in Massachusetts, United States

The Charles River is an 80-mile-long (129 km) long river in eastern Massachusetts. From its source in Hopkinton the river flows in a northeasterly direction, traveling through 23 cities and towns before reaching the Atlantic Ocean at Boston. The Native-American name for the Charles River was Quinobequin, meaning "meandering".

No visible trace remains of that system, and extensive landfills have removed all remnants of Cambridge's seaport docks and wharves. Broad Canal's truncated remnants can now be found just north of Broadway, entering the Charles River immediately north of the Longfellow Bridge.

Longfellow Bridge

The Longfellow Bridge is a steel rib arch bridge spanning the Charles River to connect Boston's Beacon Hill neighborhood with the Kendall Square area of Cambridge, Massachusetts. The bridge carries Massachusetts Route 3, the MBTA Red Line, bicycle, and pedestrian traffic. The structure was originally known as the Cambridge Bridge, and a predecessor structure was known as the West Boston Bridge; Boston also continued to use "West Boston Bridge" officially for the new bridge. The bridge is also known to locals as the "Salt-and-Pepper Bridge" due to the shape of its central towers.

East Cambridge, Cambridge, Massachusetts neighborhood of Cambridge, Massachusetts, United States

East Cambridge is a neighborhood of Cambridge, Massachusetts. Referred to in modern times as Area 1, East Cambridge is bounded by the Charles River and the Charlestown neighborhood of Boston on the east, the Somerville border on the north, Broadway and Main Street on the south, and the railroad tracks on the west. Most of the streets form a grid aligned with Cambridge Street, which was laid out to directly connect what is now the Charles River Dam Bridge with what in 1809 was the heart of Cambridge, Harvard Square. The northern part of the grid is a roughly six by eight block residential area. Cambridge Street itself is retail commercial, along with Monsignor O'Brien Highway, the Twin Cities Plaza strip mall, and the enclosed Cambridgeside Galleria. Lechmere Square is the transportation hub for the northern side. The southern half of the grid is largely office and laboratory space for hundreds of dot-com companies, research labs and startups associated with MIT, biotechnology firms including Genzyme and Biogen, the Athenaeum Press Building, light industry, an NRG Energy power station, and various small businesses. This half of the neighborhood is generally identified with Kendall Square. Along the waterfront are several hotels and taller apartment buildings.

The Malden River is a 2.3-mile-long (3.7 km) river in Malden, Medford, and Everett, Massachusetts. It is roughly 675 feet (206 m) wide at its widest point and is very narrow at its smallest point. Its banks are largely occupied by industrial business, and the river is scarcely used or even mentioned. Its water quality is worse than most local waters, including the Mystic River, into which it flows.

It is the home to Faulkner and Talbot mills and the North Billerica Train Depot. The Middlesex Canal was built through the village in 1783 and the Boston and Lowell Railroad was put through in the 1840s.

The Federal Dam is a manmade dam built across the Hudson River in the U.S. state of New York from Troy on the east bank to Green Island on the west bank. The major function of the dam is to improve navigability. It is located at mile 153 of the Hudson River, measuring from the beginning of the Hudson as a Federally Navigable Waterway near the Battery in Manhattan. The location of the dam marks the upper end of the Hudson River estuary.

Constructed over a period between 1848 and 1892, the Canal System, along with the Dam, is recognized as a Historic Mechanical Engineering Landmark by the American Society of Mechanical Engineers for its use in the development of the Venturi meter by Clemens Herschel, the first means of measuring large-scale flows, and the McCormick-Holyoke Turbine by John B. McCormick, which doubled the efficiency of turbines to more than 80% in its time.

North Point Park (Cambridge, Massachusetts)

North Point Park is an 8.5-acre (3.4 ha) park located on the Charles River in Cambridge, Massachusetts, created as mitigation for the taking of planned parkland for the construction of the Big Dig. The park opened in December 2007. It is part of the "lost half mile" of the Charles River, between the 1910 Charles River Dam, now the site of the Museum of Science and the new Charles River Dam completed in 1978. The park opening was delayed for several years by a number of logistical and bureaucratic issues, but its design, including small islands, bridges and kayaking canals, has been characterized as "grand" and "ambitious" by the local press. The park was designed by Carr Lynch & Sandell of Cambridge and Oehme, van Sweden & Associates of Washington, DC. The park is adjacent to the ongoing NorthPoint real estate development project. Just upstream of these three new parks is the Paul Dudley White Bike Path in the Charles River Reservation. The Lynch Family Skate Park is located in North Point Park under the Interstate 93 highway ramps.

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
