The Alaskan Way Viaduct is a defunct elevated freeway in Seattle, Washington, United States, that carried a section of State Route 99 (SR 99). The double-decked freeway ran north–south along the city's waterfront for 2.2 miles (3.5 km), east of Alaskan Way and Elliott Bay, and traveled between the West Seattle Freeway in SoDo and the Battery Street Tunnel in Belltown.
The viaduct was built in three phases from 1949 through 1959, with the first section opening on April 4, 1953. It was the smaller of the two major north–south traffic corridors through Seattle (the other being Interstate 5), carrying up to 91,000 vehicles per day in 2016.[1] The viaduct ran above Alaskan Way, a surface street, from S. Nevada Street in the south to the entrance of Belltown's Battery Street Tunnel in the north, following previously existing railroad lines.
The viaduct had long been viewed as a barrier between downtown and the city's waterfront, with proposals to replace it as early as the 1960s. Questions of the structure's seismic vulnerability were raised after several earthquakes damaged similar freeways in other cities, including some with the same design as the viaduct. During the 2001 Nisqually earthquake, the Alaskan Way Viaduct suffered minor damage but later inspections found it to be vulnerable to total collapse in the event of another major earthquake, necessitating its replacement.

A normal US municipal, wet-barrel fire hydrant is shown. The hydrant offers two 2½-inch (6.35cm) National Hose Thread connections and a 4½-inch (~11.43cm) National Hose Thread connection.
The modern buzzword in public safety is interoperability. The 2½-inch National Hose Thread connections are a United States nationwide standard. There's probably a small number of community water systems that use hose and hydrants with pipe thread or some other non-standard thread. Generally, one could drive a fire engine from Texas to California — or from California to Texas — and your 2½-inch hose should connect to the fire hydrants.
What's the difference between a wet barrel and a dry barrel hydrant? It's just like the name implies: a wet barrel has water inside it at all times. A dry barrel has water only after you turn it on.
Wet barrel:
* Has a valve for each opening or connection.
* Will imitate a geyser if broken off by a collision.
* Has more parts to maintain, (three valves in this case).
* Does not require you to turn off the water to add more hose connections.
* Might freeze in severe cold weather.
Dry barrel:
* Has one valve at the top of the hydrant for all openings or connections.
* Will lay on the ground and get in the way if broken off by a collision.
* Has fewer parts to maintain, (one valve in the base).
* Requires you to turn off the water during a fire to add more hose connections.
* The water below ground would have to freeze to affect the hydrant.
Need to add hose connections during a fire? If you have a dry barrel hydrant, depending on conditions everybody my have to back out of the building until the water is back on.
The fire agency, water company, county, or city water department would make decisions about what kinds of hydrants are used in your neighborhood. In the US, hydrant standards are created by American Water Works Association (AWWA) and National Fire Protection Association (NFPA).
People shown are practicing laying a five-inch supply line (hose) from a hydrant to a simulated fire scene. In my opinion, when you've done this so many times that you don't have to think about the steps, training is complete.

And liquor just make her flinch

At the start of 2016 I'll share a sunrise over the city of Izmir, that used to be Smyrna during the Greek period. Sunsets are more about what's ended, sunrises look forward. The words of the Risen Christ to the church in this town were "I know about your suffering and your poverty—but you are rich!"

Hoover Dam is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Nevada and Arizona. It was constructed between 1931 and 1936 during the Great Depression and was dedicated on September 30, 1935, by President Franklin D. Roosevelt. Its construction was the result of a massive effort involving thousands of workers, and cost over one hundred lives. Originally known as Boulder Dam from 1933, it was officially renamed Hoover Dam, for President Herbert Hoover, by a joint resolution of Congress in 1947. Since about 1900, the Black Canyon and nearby Boulder Canyon had been investigated for their potential to support a dam that would control floods, provide irrigation water and produce hydroelectric power. In 1928, Congress authorized the project. The winning bid to build the dam was submitted by a consortium called Six Companies, Inc., which began construction on the dam in early 1931. Such a large concrete structure had never been built before, and some of the techniques were unproven. The torrid summer weather and lack of facilities near the site also presented difficulties. Nevertheless, Six Companies turned the dam over to the federal government on March 1, 1936, more than two years ahead of schedule. Hoover Dam impounds Lake Mead, the largest reservoir in the United States by volume (when it is full). The dam is located near Boulder City, Nevada, a municipality originally constructed for workers on the construction project, about 30 mi (48 km) southeast of Las Vegas, Nevada. The dam's generators provide power for public and private utilities in Nevada, Arizona, and California. Hoover Dam is a major tourist attraction; nearly a million people tour the dam each year. The heavily traveled U.S. Route 93 (US 93) ran along the dam's crest until October 2010, when the Hoover Dam Bypass opened. As the United States developed the Southwest, the Colorado River was seen as a potential source of irrigation water. An initial attempt at diverting the river for irrigation purposes occurred in the late 1890s, when land speculator William Beatty built the Alamo Canal just north of the Mexican border; the canal dipped into Mexico before running to a desolate area Beatty named the Imperial Valley. Though water from the Imperial Canal allowed for the widespread settlement of the valley, the canal proved expensive to maintain. After a catastrophic breach that caused the Colorado River to fill the Salton Sea, the Southern Pacific Railroad spent $3 million in 1906–07 to stabilize the waterway, an amount it hoped in vain would be reimbursed by the Federal Government. Even after the waterway was stabilized, it proved unsatisfactory because of constant disputes with landowners on the Mexican side of the border. As the technology of electric power transmission improved, the Lower Colorado was considered for its hydroelectric-power potential. In 1902, the Edison Electric Company of Los Angeles surveyed the river in the hope of building a 40-foot (12 m) rock dam which could generate 10,000 horsepower (7,500 kW). However, at the time, the limit of transmission of electric power was 80 miles (130 km), and there were few customers (mostly mines) within that limit. Edison allowed land options it held on the river to lapse—including an option for what became the site of Hoover Dam. In the following years, the Bureau of Reclamation (BOR), known as the Reclamation Service at the time, also considered the Lower Colorado as the site for a dam. Service chief Arthur Powell Davis proposed using dynamite to collapse the walls of Boulder Canyon, 20 miles (32 km) north of the eventual dam site, into the river. The river would carry off the smaller pieces of debris, and a dam would be built incorporating the remaining rubble. In 1922, after considering it for several years, the Reclamation Service finally rejected the proposal, citing doubts about the unproven technique and questions as to whether it would in fact save money.
