Andrew P. McArdle Memorial Bridge
The Andrew P. McArdle Memorial Bridge is a steel truss bascule bridge over the Chelsea Creek, just upstream of its confluence with the Mystic River and the Tobin Bridge. Also known as the Meridian Street Bridge, it connects Meridian Street in East Boston with Pearl Street in Chelsea, Massachusetts. The bridge is a split rolling bascule, meaning that instead of pivoting on axles, the two counterweighted spans are raised by rolling on large semi-circular gears. The bridge was refurbished in 2002. According to the U.S. Federal Highway Administration 2017 National Bridge Inventory, the bridge structure's condition is poor and is " sically intolerable requiring high priority of replacement."

Wikimapia
Wikimapia is a geographic online encyclopedia project. The project implements an interactive "clickable" web map that utilizes Google Maps with a geographically-referenced wiki system, with the aim to mark and describe all geographical objects in the world. Wikimapia was created by Alexandre Koriakine and Evgeniy Saveliev in May 2006. The data, a crowdsourced collection of places marked by registered users and guests, has grown to just under 28,000,000 objects , and is released under the Creative Commons license, Creative Commons License Attribution-ShareAlike (CC BY-SA).

Chelsea Creek
Chelsea Creek, shown on federal maps as the Chelsea River, is a waterway that runs along the shore of Chelsea, Massachusetts, and separates that community from the cities of Boston and Revere, as well as feeding part of the current Belle Isle Marsh Reservation that separates Boston from Revere. It is one of 10 designated port areas in Massachusetts. The creek starts as Mill Creek at a former pond at the intersection of Revere Beach Parkway ( Massachusetts Route 16) and U.S. Route 1, now a shopping center. Mill Creek meanders east for 0.5 mile, then takes a sharp turn south, becoming Chelsea Creek, and widens significantly as it runs between Chelsea and the neighborhood of East Boston. In that area, the waterway is used by oil tankers to transport fuel to adjacent oil tanks. The creek then turns southwest and runs into the Mystic River shortly before it empties into Boston Harbor. All of the jet fuel used at Logan International Airport is stored along the Chelsea Creek, with 70 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bascule Bridge
A bascule bridge (also referred to as a drawbridge or a lifting bridge) is a moveable bridge with a counterweight that continuously balances a span, or leaf, throughout its upward swing to provide clearance for boat traffic. It may be single- or double-leafed. The name comes from the French term for balance scale, which employs the same principle. Bascule bridges are the most common type of movable span because they open quickly and require relatively little energy to operate, while providing the possibility for unlimited vertical clearance for marine traffic. History Bascule bridges have been in use since ancient times, but until the adoption of steam power in the 1850s, very long, heavy spans could not be moved quickly enough for practical application. Types There are three types of bascule bridge and the counterweights to the span may be located above or below the bridge deck. The fixed-trunnion (sometimes a "Chicago" bascule) rotates around a large axle that raises the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Boston Harbor
Boston Harbor is a natural harbor and estuary of Massachusetts Bay, and is located adjacent to the city of Boston, Massachusetts. It is home to the Port of Boston, a major shipping facility in the northeastern United States. History Since its discovery to Europeans by John Smith in 1614, Boston Harbor has been an important port in American history. Early on, it was recognized by Europeans as one of the finest natural harbors in the world due to its depth and natural defense from the Atlantic as a result of the many islands that dot the harbor. It was also favored due to its access to the Charles River, Neponset River and Mystic River which made travel from the harbor deeper into Massachusetts far easier. It was the site of the Boston Tea Party, as well as almost continuous building of wharves, piers, and new filled land into the harbor until the 19th century. By 1660, almost all imports came to the greater Boston area and the New England coast through the waters of Boston ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
