Haystack Landing Bridge
The Haystack Landing Bridge is a railroad bridge owned by Sonoma-Marin Area Rail Transit (SMART) at Haystack Landing in Petaluma, California. The original Haystack Landing bridge, which was built in 1903 and installed in 1904, was a Warren truss swing bridge built by the Pennsylvania Steel Company. It was operated by buttons on the approach trestles, and had a electric motor, as well as fabric belts and bevel gears. The turntable upon which it rotated had a diameter of . When planning out their commuter rail system, SMART estimated that it would cost approximately 20 million dollars for the bridge to be used for passenger service, so they opted for the cheaper option of buying a used drawbridge. They decided upon the old Galveston Causeway railroad bridge, that was planned to be scrapped. SMART budgeted around 16 million dollars for the new bridge and purchased the bridge for 4.2 million dollars. Officials say the bridge should be good for around 75 to 80 years of passenger ra ...

Petaluma River
The Petaluma River is a river in the California counties of Sonoma and Marin that becomes a tidal slough for most of its length. The headwaters are in the area southwest of Cotati. The flow is generally southward through Petaluma's old town, where the waterway becomes navigable, and then flows another through tidal marshes before emptying into the northwest corner of San Pablo Bay. History The word Petaluma may derive from the Miwok words ''pe’ta'', flat, and ''luma'', back. The Miwok people lived in Sonoma County for more than 2500 years. Petaluma was the name of a village on a low hill east of Petaluma creek and north east of the present day town of Petaluma. The first recorded exploration of the Petaluma River was by Captain Fernando Quiros in October, 1776. While other members of his Spanish expedition collected adobe and timber for the new Presidio of San Francisco and for the Mission San Francisco de Asís (Mission Dolores), Quiros and his sailors tried unsuccessfully ...

Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Standard Gauge
A standard-gauge railway is a railway with a track gauge of . The standard gauge is also called Stephenson gauge (after George Stephenson), International gauge, UIC gauge, uniform gauge, normal gauge and European gauge in Europe, and SGR in East Africa. It is the most widely used track gauge around the world, with approximately 55% of the lines in the world using it. All high-speed rail lines use standard gauge except those in Russia, Finland, and Uzbekistan. The distance between the inside edges of the rails is defined to be 1435 mm except in the United States and on some heritage British lines, where it is defined in U.S. customary/Imperial units as exactly "four feet eight and one half inches" which is equivalent to 1435.1mm. History As railways developed and expanded, one of the key issues was the track gauge (the distance, or width, between the inner sides of the rails) to be used. Different railways used different gauges, and where rails of different gauge met – ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Bridge Company
The American Bridge Company is a heavy/civil construction firm that specializes in building and renovating bridges and other large, complex structures. Founded in 1900, the company is headquartered in Coraopolis, Pennsylvania, a suburb of Pittsburgh. The firm has built many bridges in the U.S. and elsewhere; the Historic American Engineering Record notes at least 81.

Pittsburgh-Des Moines Steel Co
The Pittsburgh-Des Moines Steel Company (originally the Des Moines Bridge and Iron Company), and often referred to as Pitt-Des Moines Steel or PDM was an American steel fabrication company. It operated from 1892 until approximately 2002 when its assets were sold to other companies, including Chicago Bridge & Iron Company. The company began as a builder of steel water tanks and bridges. It also later fabricated the "forked" columns for the World Trade Center in the 1960s, and was the steel fabricator and erector for the Gateway Arch in St. Louis. A number of its works are listed on the National Register of Historic Places. History The company was founded in 1892 by two graduates of Iowa State College, William H. Jackson and Berkeley M. Moss. The partners initially contracted to have their steel tanks fabricated by Keystone Bridge Company of Pittsburgh, but soon took on a third partner, Edward W. Crellin, who was operating a small fabricating shop in Des Moines, Iowa. It was at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Haystack Landing was a passenger and freight connection on San Francisco Bay via the Petaluma River and San Pablo Bay. The landing is currently the site of a historic Steamboat, steamer dock, a railroad bridge, and of a planned Asphalt concrete, asphalt production and storage facility.

The Petaluma and Haystack Railroad was founded, built, and then attached to the steamer dock at Haystack Landing, with service beginning on August 1, 1864. This railroad was only the third railro ...
