Deer Isle Bridge
The Deer Isle Bridge is a suspension bridge spanning Eggemoggin Reach in the state of Maine. The bridge is the only vehicular connection from the Maine mainland to Little Deer Isle, one of the segments that make up the island. The span was completed in March 1939 with a main span of . The bridge was designed by Holton Duncan Robinson and David Bernard Steinman. It encountered wind stability problems that were similar to those of the Whitestone Bridge and the original Tacoma Narrows Bridge, which collapsed shortly after it opened. The problems led to modifications which included numerous cable stays connecting cables to the tower and tower to the deck. The span today carries two narrow lanes of State Route 15. A re-decking project was completed in May 2008. Repainting started in mid-2010 has been completed. History The Deer Isle-Sedgwick Bridge, named for the two townships it connects, was the first bridge built between Deer Isle and the mainland, replacing an inadequate ferry cr ...

Deer Isle, Maine
Deer Isle is a town in Hancock County, Maine, United States. The population was 2,194 at the 2020 census. Notable landmarks in Deer Isle are the Haystack Mountain School of Crafts, Stonington Opera House, and the town's many art galleries. History The town was incorporated in 1789, at which time it included the islands of Little Deer Isle, Deer Isle, and Isle au Haut. Deer were abundant on these islands, hence the name. In 1868 Isle au Haut became a separate town. In 1897, the southern third of Deer Isle incorporated as the town of Stonington.

Historic American Engineering Record In Maine
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...

Road Bridges In Maine
A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels", whi ...

Bridges Completed In 1939
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use.

Historic American Engineering Record
Heritage Documentation Programs (HDP) is a division of the U.S. National Park Service (NPS) responsible for administering the Historic American Buildings Survey (HABS), Historic American Engineering Record (HAER), and Historic American Landscapes Survey (HALS). These programs were established to document historic places in the United States. Records consist of measured drawings, archival photographs, and written reports, and are archived in the Prints and Photographs Division of the Library of Congress. Historic American Buildings Survey In 1933, NPS established the Historic American Buildings Survey following a proposal by Charles E. Peterson, a young landscape architect in the agency. It was founded as a constructive make-work program for architects, draftsmen and photographers left jobless by the Great Depression. It was supported through the Historic Sites Act of 1935. Guided by field instructions from Washington, D.C., the first HABS recorders were tasked with docume ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suspension Bridge
A suspension bridge is a type of bridge in which the deck (bridge), deck is hung below suspension wire rope, cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world. Besides the bridge type most commonly called suspension bridges, covered in this article, there are other types of suspension bridges. The type covered here has cables suspended between towers, with vertical ''suspender cables'' that transfer the Structural load#Live load, imposed loads, transient load, live and Structural load#Dead load, dead loads of the deck below, upon which traffic crosses. This arrangement allows the deck to be level or to arc upward for additional clearance. Like other suspension bridge types, this type often is constructed without the use of falsework. The suspension cables must be anchored at each end of the bridge, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Merritt-Chapman & Scott
Merritt-Chapman & Scott, nicknamed "The Black Horse of the Sea", was a noted marine salvage and construction firm of the United States, with worldwide operations. The chief predecessor company was founded in the 1860s by Israel Merritt, but a large number of other firms were merged in over the course of the company's history. It was taken over in the 1950s by famed corporate raider, Louis E. Wolfson. It ceased operation in the late 1960s or early 1970s. Early history The 1850s and 1860s were a dangerous time for mariners and marine operations around the American continent. The transition from sail to steam with the consequent unreliability of equipment, and the growing needs of commerce to fuel US expansion meant that a large number of ships operated. Some foundered or got into trouble on their own, and some were lured to their doom by wreckers. Salvage operations were in their infancy, and commercial diving was almost unheard of. It was with this background that a number of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
State Route 15 (Maine)
State Route 15 (SR 15) is a numbered state highway in Maine, United States. SR 15 runs over from Stonington in the south to Jackman in the north. Route description SR 15 begins in the town of Stonington, at the intersection of Main Street, School Street, and West Main Street. The route proceeds north out of Stonington and through Deer Isle en route to the mainland of Maine. Upon leaving the islands to the south via the Deer Isle Bridge, SR 15 meets SR 175 and forms an approximately concurrency with it. SR 15 then splits off 175 and then joins SR 176 farther to the north. The two routes continue into Blue Hill, where SR 15 turns northward, while 176 goes to the east.
