Amelia Earhart Dam

The Amelia Earhart Dam is an earth-fill dam spanning the Mystic River near its mouth between Somerville and Everett, Massachusetts. It was built in 1966 to regulate tidal effects and the incursion of salt water in the upstream river basin. The dam is named after the aviation pioneer Amelia Earhart whose plane disappeared in 1937. Earhart lived in nearby Medford, Massachusetts in the 1920s. There is no public access to the dam. Technical Details The Amelia Earhart Dam has 3 locks for marine traffic, the largest is 325 feet long, and 45 feet wide; the two smaller locks are 120 feet long and, 22 feet wide. It is equipped with pumps to push fresh water out to the harbor even during high tide. Fish passage Four dams play a role in the passage of fish into the Mystic River system. The Amelia Earhart Dam is the first and the largest, but it is not considered the main obstacle for the passage of fish like river herring because dam operations guarantee that fish can pass through at low tide and when the locks open. History The Amelia Earhart Dam replaced the Craddock Locks in the city of Medford. The Craddock Locks were built in 1909 to prevent excess floodwaters from engulfing the city, Remnants of the locks can be seen under the Cradock Bridge. The 1966 construction of the dam opened more land along the Mystic River for development, as it stabilized water levels and prevented saltwater intrusion. The City of Somerville's 2017 Climate Change Vulnerability Assessment noted that by 2035, a 100-year flood would flank the dam, and by 2070, overtop it, leading to major impacts on low-lying areas such as Assembly Square. In January 2018, a nor'easter caused slushy coastal flooding in downtown Boston and the Seaport district, alarming local officials. In March 2018, a storm caused minor flooding in Draw Seven Park, and ocean water nearly overtopped the dam. In November 2018, 21 cities and towns near the Mystic River requested flood prevention and mitigation funding, including approximately $20 million for an additional pump. Planned improvements Overtopping of the dam by a storm surge could flood thousands of buildings, and parts of the MBTA Orange Line and Interstate 93. The Massachusetts Department of Conservation and Recreation (DCR) announced an investment of $28 million to improve climate resiliency and provide significant flood protection for the environmental justice communities surrounding the Amelia Earhart Dam (AED) on the Mystic River between Somerville and Everett and Draw Seven Park in Somerville. The projects are funded through the American Rescue Plan Act (ARPA). The improvements include $13 million to redesign the elevation of the dam and $15 million for the renovation of Draw Seven Park including construction of a flood control berm to prevent coastal flooding.

First Church in Salem

First Church in Salem (officially known as the First Church in Salem, Unitarian Universalist) is a Unitarian Universalist church in Salem, Massachusetts that was designed by Solomon Willard and built in 1836. History Before the church was built, around 1635, its members had to gather in houses or a building near the Town House Square. The congregation claims to be "one of the oldest continuing Protestant churches in North America and the first to be governed by congregational polity, a central feature of Unitarian Universalism". The values of the Puritans who founded the First Church in Salem stated that they were on a pilgrimage to the city of God. This made them want to perfect their world and community. It also made some of their members such as third minister Roger Williams, activists in the community. He specifically argued that Native Americans should be compensated for their land and that the colonial government should not have power over the church. Thomas Treadwell Stone became minister of the church on July 12, 1846. In December 1851, the Salem Female Anti-Slavery Society held their annual general meeting at the church. For twelve years, Charles Wentworth Upham was minister of the church. Grace Parker commissioned a stained-glass window for the church in dedication to her late husband, George Swinnerton Parker of Parker Brothers fame, and their two sons.

Oak Grove Cemetery (Falmouth, Massachusetts)

The Oak Grove Cemetery is an historic cemetery on Jones Road in Falmouth, Massachusetts. Overview The private cemetery was established in 1849 with the initial purchase of 5 acres (2.0 ha) of land fronting on Palmer Road. This original section of the cemetery was laid out in the then-popular rural cemetery style, with winding lanes. The cemetery was enlarged in 1886, 1939, and 1952, with the 1939 purchase including the section facing Jones Road that now serves as its main entrance. Its Colonial Revival chapel was built in 1935 with funding by a bequest of Elizabeth G. Parke. The cemetery is the burying ground for many of Falmouth's most important citizens, including most of its veterans (including those from the American Revolutionary War and the War of 1812 which were relocated from family cemeteries), and ship captains who were the town's leading citizens in the 19th century. One of its most famous burials is that of Katharine Lee Bates, author of "America The Beautiful". The cemetery was listed on the National Register of Historic Places in 2014. Notable burials Frank Barrows (1844–1922), Major League Baseball player for the Boston Red Stockings Katharine Lee Bates (1859–1929), author of America the Beautiful Sylvia Donaldson (1849–1937), one of the first women elected to the Massachusetts House of Representatives Robert Emmons (1872–1928), football player and coach, yachtsman, and millionaire Irvin McDowell Garfield (1870–1951), son of president James A.

Mendon Twin Drive-In

The Mendon Twin Drive-In is a drive-in theater in Mendon, Massachusetts. Opened on June 14, 1954, it is currently owned by Dan Andelman and his brothers Dave Andelman and Michael, who purchased the drive-in in March 2014 from Susan Swanson and Kathy Gorman, who had operated it since 1986. Dave was ousted from his ownership role in 2020 due to his negative comments on the Black Lives Matter protests. It can accommodate 800 cars. The second screen was added in 1998. Both screens broadcast movie soundtracks using FM radio signals; there are no remaining metal audio speakers on the poles. As of 2015, it was one of three remaining drive-Ins in Massachusetts. The Andelmans have added a 5,000-square-foot outdoor patio where they offer beer and wine. References External links Official Website
Kendall Cogeneration Station

The Kendall facility is an energy facility owned by Vicinity Energy that produces steam and electricity to the cities of Boston and Cambridge. Owned by GenOn Energy in 2012, in 2013 Veolia Energy North America purchased the plant from NRG Energy. In 2020, Antin Infrastructure Partners acquired Veolia Energy North America and renamed it Vicinity Energy. History The Kendall power plant was built in 1949, operating in "relative obscurity" for some time as it was only turned on when high energy levels were demanded. In 2003, the power plant switched to natural gas from oil and became more active. In 2004, there were complaints from environmentalists that water intake and water discharge was damaging marine life. A 2006 permit issued by federal and state environmental officials was appealed by power plant officials on the grounds of being too strict. The plan for the GenOn Kendall Cogeneration Station to slice its hot water discharge was revealed in February 2011. It had been negotiated along with the Environmental Protection Agency New England office and state regulators. The plan called for converting hot water to steam to be sent to Boston, possibly by a pipe. The agreement ended "a six-year battle between the plant’s operators and environmentalists over its state and federal water discharge permits." Veolia Energy North America was working on the pipe, to be completed by 2016. As such, waste heat from the Kendall Cogeneration Station in Cambridge would heat buildings in Boston. The pipeline extension was completed in 2013. In January 2012, the station had a production capacity of 256 megawatts, and in 2010 produced roughly 717,000 metric tons of carbon dioxide. While it used natural gas primarily, it also had oil as a backup to produce both electricity and steam energy. In 2012, the plant was owned by GenOn Energy. In 2013 Veolia Energy North America purchased the plant from NRG Energy. In 2020, Antin Infrastructure Partners acquired Veolia Energy North America and renamed it Vicinity Energy. In 2024, Vicinity Energy installed a 42-megawatt electric-powered boiler. Demolition necessary for installation of a 35-megawatt industrial heat pump began in 2025. The heat pump will use water from the Charles River for district heating of about 70 million square feet of buildings in Boston and Cambridge. Notes External links www.vicinityenergy.us
North Cambridge carhouse

The North Cambridge carhouse is a bus garage for trolleybuses, and a former streetcar carhouse, in Cambridge, Massachusetts, which is owned and operated by the Massachusetts Bay Transportation Authority (MBTA). It was first built in 1874. The current structure dates from 1979 and is located in the North Cambridge neighborhood at 2375 Massachusetts Avenue. It is one of two MBTA garages used in operation of the Boston-area trolleybus system (along with the Southampton Garage, where Silver Line dual-mode buses are maintained). History The carhouse and yard date to the 1874 construction of a brick building with a clock tower that was constructed by the Union Railway. It remained in use until 1889 when the replacement of horsecars by electric streetcars made the structure obsolete. In 1897, the West End Street Railway constructed a larger structure, which existed for the next forty years until it was demolished in 1937. In 1979, the present structure was constructed to house the trolley buses which became active on the line in 1958. The carhouse was the northern terminus of route 77A, which operated as a short turn of the 77 to supply trolleybuses for the 71, 72, and 73 routes. Trolleybus service ended in March 2022. The MBTA is retrofitting the facility to accommodate battery electric buses. A $27.3 million construction contract was issued in October 2023. As of December 2025 the garage modifications are complete. Bus service from the garage is expected to start in summer 2026.

Northfield Mountain (hydroelectricity facility)

Northfield Mountain is a pumped-storage hydroelectric plant and reservoir located on and under the similarly named Northfield Mountain in Erving and Northfield, Massachusetts. It is currently owned by FirstLight Power Resources (formerly NE Energy), which purchased the facility from Northeast Utilities in 2006. History Engineering studies for the plant began in October 1964, with early site preparation starting three years later. In 1972 its 1,168 megawatt hydroelectric plant became operational as the largest such facility in the world. The facility was built to balance the supply from the nearby Vermont Yankee Nuclear Power Plant. Design The plant was built entirely underground, and located about 5.5 miles (8.9 km) up the Connecticut River from Turners Falls Dam. A stretch of the Connecticut River, extending some 20 miles (32 km) north from this dam to the Vernon Dam, Vermont, serves as the station's lower reservoir. During periods of lower electrical power demand, the plant pumps water from this lower reservoir through the Northfield Mountain Tailrace Tunnel to a man-made upper reservoir. At times of high demand, water is released to flow downhill from this upper reservoir through a turbine generator, where it then collects in the lower reservoir to be stored until again pumped to the upper reservoir. Northfield Mountain's upper reservoir covers 300 acres (120 ha) at 800 feet (240 m) above the river, with total storage of 17,186 acre-feet (21.199 GL) of water. Its underground powerhouse lies at 700 feet (210 m) below the surface and is accessible through a 2,500-foot (760 m)-long tunnel; it includes four large reversible turbines, each of which can pump 15,200 cubic feet (430 m3) of water per second and release 20,000 cubic feet (570 m3) of water per second to generate 1,168 MW of electricity. The turbines can ramp up in 10 minutes, and deliver full power for 8 hours. The plant also has a solar farm with a capacity of 2MW. It was added in 2011. Controversy The plant was built to store excess energy from the Vermont Yankee Nuclear Power Plant, but that plant was shut down in 2014. The pumped-storage plant is still in operation, but according to activist site Connecticut River Defenders it is no longer needed, as it is only storing energy from fossil-fuel plants, and is harming the Connecticut River ecosystem, killing all river life that passes through its turbines. These claims, particularly about the plant exclusively storing fossil fuel power have had to be retracted. References External links Official website
ГАЕС Northfield Mountain

ГАЕС Northfield Mountain — гідроакумулювальна електростанція у штаті Массачусетс (Сполучені Штати Америки). Як нижній резервуар станція використовує водосховище ГЕС Turners Falls, створене на річці Коннектикут (дренує східну сторону Аппалачів та впадає до протоки Лонг-Айленд). Ця водойма, витягнута по долині річки на 32 км, має площу поверхні 8,5 км2 та припустиме коливання рівня в операційному режимі між позначками 53,6 та 56,4 метра НРМ, що забезпечує корисний об'єм у 19,9 млн м3. Цих параметрів досягнуто саме в межах проєкту ГАЕС, для чого збільшили розташовану в лівій протоці Коннектикуту бетонну греблю Montague (висота 11 метрів, довжина 192 метри) та спорудили у правій протоці нову бетонну греблю Gill (висота 17 метрів, довжина 150 метрів). Верхній резервуар створили на лівобережжі річки за допомогою греблі висотою 43 метри, довжиною 1600 метрів та товщиною по гребеню 9 метрів, і трьох допоміжних дамб висотою від 8 до 14 метрів та загальною довжиною 1501 метр. Разом вони утримують водосховище з площею поверхні 1,2 км2 та корисним об'ємом 15,2 млн м3, у якому припустиме коливання рівня в операційному режимі між позначками 286 та 305 метрів НРМ. З верхнього резервуара через канал довжиною 0,6 км і напірну шахту глибиною 24 метри ресурс потрапляє до водоводу завдовжки 0,25 км з діаметром 9,4 метра. Останній розгалужується спершу на два, а потім на чотири водоводи з кінцевим діаметром 2,9 метра, котрі живлять розташовані у підземному машинному залі розмірами 100х21 метр чотири оборотні турбіни загальною потужністю 1167 МВт. Гідроагрегати станції використовують напір від 230 до 251 метра та мають проєктний виробіток на рівні 1382 млн кВт·год електроенергії на рік, при цьому на закачування води витрачається 1437 млн кВт·год. З нижнім резервуаром вони пов'язані через тунель завдовжки 1,6 км з перетином 10 × 9,4 метра. Зв'язок з енергосистемою відбувається по ЛЕП, розрахованій на роботу під напругою 345 кВ. Примітки
Sandwich Glass Museum

Sandwich Glass Museum is a town history museum in Sandwich, Massachusetts, featuring a wide range of rare glass, including Victorian era glass manufactured by the now defunct local Boston & Sandwich Glass Factory, founded in Sandwich by Deming Jarves in 1825. The Sandwich Glass Works primarily manufactured pressed lead-based glass, and was known for its use of color. The museum also has a live glass blower, exhibits detailing the creation and coloring of various types of rare glass, as well as rotating exhibits of contemporary studio glass art from local and regional artists. It has a furnace for clear glass heated to 2200 deg F that it runs 24x7 that shuts down only once every five years, and a computerized annealing oven to slowly cool down new creations over a full day to help prevent cracking. Live demonstrations of the craft of glassblowing are held every hour on the hour and last for 15 minutes. The demonstrations include glass-blowing, shaping, mold-forming and adding bits of glass color known as frit. The objects created during the demo change day to day, influenced by the time of year and nearby holidays. The museum also has a historical movie that plays once per hour, as well as a series of galleries each focused on a time period or glass creation techniques. There is a shop at the end featuring contemporary studio glass, primarily from regional artists, as well as museum-created items. References External Sandwich Glass Museum
St. Mark's Episcopal Church (Boston, Massachusetts)

St. Mark's Episcopal Church is a historic church complex at 73 Columbia Road in the Dorchester neighborhood of Boston, Massachusetts. The complex consists of three buildings: a chapel, rectory, and parish hall. All three were built between 1904 and 1909, with the last significant alteration to the exterior of the church occurring in 1916. All three buildings were designed by Edmund O. Sylvester, and present a unified architectural statement of Craftsman styling with some English Gothic (Tudor Revival) detailing. The church complex was listed on the National Register of Historic Places in 2014. The congregation was established as a mission in 1887 after fire destroyed the St. Mary's Church on Bowdoin Street on June 15, and a portion of its congregation began to meet in the Grove Hall area of Dorchester. St. Mary's Mission carried on until October 31, 1897. An independent mission was organized a week later, which adopted the name "St. Mark's" on March 13, 1898, and which acquired land on Columbia Road to build a church in early October. The cornerstone for the new church was laid April 25, 1904, and the first service held on September 18. The congregation was formally incorporated as a parish on January 15, 1906. The church reported 95 members in 2017 and 129 members in 2023; no membership statistics were reported in 2024 parochial reports. Plate and pledge income reported for the congregation in 2024 was $86,336 with average Sunday attendance (ASA) of 57 persons.

Leverett Circle Connector Bridge

Die Leverett Circle Connector Bridge (auch Storrow Drive Connector Bridge) ist eine stählerne Kastenträgerbrücke im Bundesstaat Massachusetts der Vereinigten Staaten. Sie führt je zwei Fahrspuren in nördlicher und südlicher Fahrtrichtung über den Charles River und verbindet dabei die Interstate 93 an ihrem nördlichen Ende in Somerville mit dem Storrow Drive und Leverett Circle an ihrem südlichen Ende in Boston. Das Bauwerk wurde ebenso wie die benachbarte Leonard P. Zakim Bunker Hill Memorial Bridge im Zuge des Big Dig errichtet und konnte eine Woche vor dem Plan am 7. Oktober 1999 eröffnet werden. Während der Bauphase wurde sie aufgrund des deutlichen Unterschieds zur Zakim-Brücke auch Baby Bridge genannt. Die Brücke ist die größte Kastenträgerbrücke in den Vereinigten Staaten. Sie wurde im Jahr 2001 mit dem „Prize Bridge“ der National Steel Bridge Alliance (NSBA) ausgezeichnet. Siehe auch Liste der Brücken über den Charles River Einzelnachweise
Leverett Circle Connector Bridge

The Leverett Circle Connector Bridge is a 1.7 mile-long highway bridge over the Charles River in Boston, Massachusetts, carrying two lanes each of northbound and southbound traffic. It connects to Interstate 93 (I-93) at the northern end (exit 18, formerly 26 from I-93 south) and splits at the southern end, providing direct access to both Storrow Drive and Leverett Circle in Boston. Going northbound, there is also a fork which provides access to the City Square Tunnel under Charlestown to proceed on U.S. Route 1 (US 1) northbound via the Tobin Bridge. The span was built in conjunction with the more dramatic Leonard P. Zakim Bunker Hill Bridge as part of the Central Artery/Tunnel Project, widely known as the Big Dig. During construction, the Leverett Circle Connector Bridge was sometimes called "Baby Bridge". The bridge opened for traffic on October 7, 1999, at a cost of $22.27 million (equivalent to $39.3 million in 2024). Also known as the Storrow Drive Connector, it is the largest steel box girder bridge in the United States. It was the winner of a July 2001 National Steel Bridge Alliance (NSBA) "prize bridge" award. Its weaving design was determined by the other major structures involved in the Big Dig but unlike other parts of the project, it was finished eight days ahead of schedule. Major intersections The entire route is in Boston, Suffolk County. All exits are unnumbered. Gallery See also Engineering portal Massachusetts portal Transport portal References
