Squirrel Bridge
A squirrel bridge is a construction (similar to a wildlife crossing) which enables small animals, especially squirrels and martens, to safely cross busy roadways. The bridges are a measure for wildlife management and natural habitat preservation, and serve the functions of both animal welfare and accident prevention. The Nutty Narrows Bridge in Longview, Washington, built in 1963, is regarded as the first of its kind. The city has since built eight other bridges for squirrels. Costs to construct squirrel bridges vary significantly, depending on construction. Simple rope bridge constructions, such as those in Brecht, Belgium, have cost only about 250 euros, while the bridge built in The Hague in 2013 took half a year to construct and cost 150,000–200,000 euros. List of squirrel bridges The following bridges protect the red squirrel, common in Europe, or the North American gray squirrel (either of which may be hunted as an invasive species depending on the continent).

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] |

Gantry (road Sign)
A gantry (also known as a sign holder, road sign holder, sign structure or road sign structure) is a traffic sign assembly in which signs are mounted or railway signals are supported on an overhead support. They also often contain the apparatus for traffic monitoring systems and cameras, or open road tolling systems. Gantries are usually built on high-traffic roads or routes with several lanes, where signs posted on the side of the highway would be hard for drivers to see. Gantries may be cantilevered or one sided on the left, right and center (sometimes referred to as a half-gantry or Butterfly gantry), or they may be bridges with poles on each side. Similar gantries are used in railway signalling or to suspend overhead lines on multi-track lines. Around the world Canada Gantry signs are commonly used in urban highways in Canada to support overhead signs. Half-gantries are used to place signs near exits where space does not permit having signs to the right side of the ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brussels
Brussels (french: Bruxelles or ; nl, Brussel ), officially the Brussels-Capital Region (All text and all but one graphic show the English name as Brussels-Capital Region.) (french: link=no, Région de Bruxelles-Capitale; nl, link=no, Brussels Hoofdstedelijk Gewest), is a region of Belgium comprising 19 municipalities, including the City of Brussels, which is the capital of Belgium. The Brussels-Capital Region is located in the central portion of the country and is a part of both the French Community of Belgium and the Flemish Community, but is separate from the Flemish Region (within which it forms an enclave) and the Walloon Region. Brussels is the most densely populated region in Belgium, and although it has the highest GDP per capita, it has the lowest available income per household. The Brussels Region covers , a relatively small area compared to the two other regions, and has a population of over 1.2 million. The five times larger metropolitan area of Brusse ...

Fremont Bridge (Portland, Oregon)
The Fremont Bridge is a steel tied-arch bridge over the Willamette River located in Portland, Oregon, United States. It carries Interstate 405 and US 30 traffic between downtown and North Portland where it intersects with Interstate 5. It has the longest main span of any bridge in Oregon and is the second longest tied-arch bridge in the world (after Caiyuanba Bridge across the Yangtze River, China). The bridge was designed by Parsons, Brinckerhoff, Quade and Douglas, and built by Murphy Pacific Corporation. The bridge has two decks carrying vehicular traffic, each with four lanes. The upper deck is signed westbound on US 30 and southbound on I-405. The lower deck is signed eastbound on US 30 and northbound on I-405. Design and construction Due to the public's dissatisfaction with the appearance of the Marquam Bridge, the Portland Art Commission was invited to participate in the design process of the Fremont. The improvement in visual quality resulted in a bridge that was n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tied-arch Bridge
A tied-arch bridge is an arch bridge in which the outward horizontal forces of the arch(es) caused by tension at the arch ends to a foundation are countered by equal tension of its own gravity plus any element of the total deck structure such great arch(es) support. The arch(es) have strengthened chord(s) that run to a strong part of the deck structure or to independent tie-rods below the arch ends. Description Thrusts downwards on a tied-arch bridge deck are translated, as tension, by vertical ties between the deck and the arch, tending to flatten it and thereby to push its tips outward into the abutments, like for other arch bridges. However, in a tied-arch or bowstring bridge, these movements are restrained not by the abutments but by the strengthened chord, which ties these tips together, taking the thrusts as tension, rather like the string of a bow that is being flattened. Therefore, the design is also called a bowstring-arch or bowstring-girder bridge. The elimination o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lewis And Clark Bridge (Columbia River)
The Lewis and Clark Bridge is a cantilever bridge that spans the Columbia River between Longview, Washington, and Rainier, Oregon. At the time of its completion, it had the longest cantilever span in the United States. The bridge was opened on March 29, 1930, as a privately owned bridge named the Longview Bridge. The $5.8 million cost (equivalent to $ million in dollars) was recovered by tolls, $1.00 for cars and $0.10 for pedestrians (equivalent to $ for cars and $ for pedestrians in dollars). At the time it was the longest and highest cantilever bridge in the United States. The state of Washington (state), Washington purchased the bridge in 1947 and the tolls were removed in 1965 after the bridge was paid for. In 1980, the bridge was rededicated as the Lewis and Clark Bridge in honor of the Lewis and Clark Expedition. The deck was replaced in 2003–04 at a cost of $29.2 million. The bridge is long with of vertical clearance. The main span is long and the top of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Truss Bridge
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with strength to maintain its own shape, and th ...
