Norwalk Harbor
Norwalk Harbor is a recreational and commercial harbor and seaport at the estuary of the Norwalk River where it flows into Long Island Sound in Norwalk, Connecticut, United States. The last portion of the Norwalk River from the head of navigation near Wall Street in Central Norwalk to the Long Island Sound forms Norwalk Harbor. It is a federal navigation channel of the "recreational and small commercial harbor" variety.The U.S. Army Corps of Engineers classifies a port as "deep water" if the channel is or more deep. Norwalk's is not that deep. In and around the harbor there are 15 marinas, 13 private clubs with boating facilities, and 5 commercial port facilities. There are more than 1800 berthing spaces and more than 500 harbor mooring locations. About 800 boats may be launched from storage racks at marinas and clubs as well as via the city maintained launching ramp in Veterans Park. More than 2700 commercial vessel trips to and from the harbor occur each year. The ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Connecticut Route 136
Route 136 is a state highway in southwestern Connecticut, running from Darien to Easton. The route was initially established in 1932 to serve the beach communities between Darien and Southport. Its eastern end was relocated in 1963 to head northeast from Westport to Easton instead. Route description Route 136 begins at an intersection with US 1 in Darien and heads east, intersecting I-95 before crossing into Norwalk. In Norwalk, it continues south, east, and northeast through the Rowayton section of the city before a section maintained by the city between the intersection of Wilson and Meadow Streets and the intersection of Water and Washington Street, after which it continues east across the Norwalk River, through a triangular one-way couplet and into Westport. In Westport, Route 136 turns northeast along the Saugatuck River, intersecting I-95 again before crossing the Saugatuck (via the Saugatuck River Bridge), briefly overlapping Route 57, passing beneath Route 15 w ...

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] |
National Register Of Historic Places
The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures and objects deemed worthy of preservation for their historical significance or "great artistic value". A property listed in the National Register, or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred in preserving the property. The passage of the National Historic Preservation Act (NHPA) in 1966 established the National Register and the process for adding properties to it. Of the more than one and a half million properties on the National Register, 95,000 are listed individually. The remainder are contributing resources within historic districts. For most of its history, the National Register has been administered by the National Park Service (NPS), an agency within the U.S. Department of the Interior. Its goals are to help property owners and inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Swing Bridge
A swing bridge (or swing span bridge) is a movable bridge that has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the swing span (turning span) can then pivot horizontally as shown in the animated illustration to the right. Small swing bridges as found over canals may be pivoted only at one end, opening as would a gate, but require substantial underground structure to support the pivot. In its closed position, a swing bridge carrying a road or railway over a river or canal, for example, allows traffic to cross. When a water vessel needs to pass the bridge, road traffic is stopped (usually by traffic signals and barriers), and then motors rotate the bridge horizontally about its pivot point. The typical swing bridge will rotate approximately 90 degrees, or one-quarter turn; however, a bridge which intersects the navigation channel at an oblique angle may be built to rotate only 45 degrees, or ...

Norwalk River Railroad Bridge
The Norwalk River Railroad Bridge (also known as the Walk Bridge) is a swing bridge built in 1896 for the New York, New Haven and Hartford Railroad. It currently carries Amtrak and Metro-North Railroad trains over the Norwalk River. The current swing bridge is located at the same site where, in 1853, a train from New York City plummeted into the river while the previous swing bridge was open, resulting in dozens of deaths. In 1896, the New Haven Railroad built the bridge and widened its route to four tracks, as it simultaneously built its South Norwalk Railroad Bridge over the intersection of Washington Street with North Main and South Main streets. The span, with a rotating swing span long was provided by the Berlin Iron Bridge Co. This type of swing bridge is one of just two on the Northeast Corridor. and The swing span has a rim-bearing system of 96 rollers, allowing tall vessels to pass by. The span is one of only 13 of the company's bridges (and one of only two railr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Connecticut Turnpike
The Connecticut Turnpike (officially the Governor John Davis Lodge Turnpike) is a controlled-access highway and former toll road in the U.S. state of Connecticut; it is maintained by the Connecticut Department of Transportation (ConnDOT). Spanning approximately along a generally west–east axis, its roadbed is shared with Interstate 95 (I-95) for from the New York state border in Greenwich to East Lyme; I-395 for from East Lyme to Plainfield; and State Road 695 (SR 695) for from Plainfield to the Rhode Island state line at U.S. Route 6 (US 6) in Killingly. The turnpike briefly runs concurrently with US 1 from Old Saybrook to Old Lyme and Route 2A from Montville to Norwich. Construction on the Connecticut Turnpike began in 1954 and the highway was opened in 1958. It originally followed a sequential exit numbering system that disregarded route transition, where the exit numbers on I-395 were a continuation of the exit numbers on I-9 ...

Girder Bridge
A girder bridge is a bridge that uses girders as the means of supporting its deck. The two most common types of modern steel girder bridges are plate and box. The term "girder" is often used interchangeably with "beam" in reference to bridge design. However, some authors define beam bridges slightly differently from girder bridges. A girder may be made of concrete or steel. Many shorter bridges, especially in rural areas where they may be exposed to water overtopping and corrosion, utilize concrete box girder. The term "girder" is typically used to refer to a steel beam. In a beam or girder bridge, the beams themselves are the primary support for the deck, and are responsible for transferring the load down to the foundation. Material type, shape, and weight all affect how much weight a beam can hold. Due to the properties of the second moment of area, the height of a girder is the most significant factor to affect its load capacity. Longer spans, more traffic, or wider spacing o ...

Arch Bridge
An arch bridge is a bridge with abutments at each end shaped as a curved arch. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side. A viaduct (a long bridge) may be made from a series of arches, although other more economical structures are typically used today. History Possibly the oldest existing arch bridge is the Mycenaean Arkadiko Bridge in Greece from about 1300 BC. The stone corbel arch bridge is still used by the local populace. The well-preserved Hellenistic Eleutherna Bridge has a triangular corbel arch. The 4th century BC Rhodes Footbridge rests on an early voussoir arch. Although true arches were already known by the Etruscans and ancient Greeks, the Romans were – as with the vault and the dome – the first to fully realize the potential of arches for bridge construction.
