1 May 2010: This video is a 9-minute extraction from my 17-minute original video shot on 1 May 2010 beginning around 2:30pm at the 6th Ave RTD Bridge installation site here in Lakewood, CO.

RTD’s FasTracks
The 6th Avenue Bridge
West Corridor at a Glance
The West Corridor light rail project is part of FasTracks – RTD’s voter-approved 12-year comprehensive plan to expand quality transit service in the Denver metro region.
The West Corridor is a 12.1-mile light rail transit corridor extending from Denver Union Station to Jefferson County, through Denver, Lakewood, and Golden.
Twelve stations are proposed for the West Corridor including Auraria West, Decatur/Federal, Knox, Perry, Sheridan, Lamar, Wadsworth, Garrison, Oak, Federal Center, Red Rocks Community College and Jeffco Government Center.
The ridership projection is 29,700 per day by 2030.
Major construction began in 2009 with the line projected to open in 2013.
Part of this effort includes a bridge designed to span over 6th Avenue between Kipling and Simms/Union in Lakewood.
The Bridge
Structure: The structure is 286′ long and 65′ tall from top of crown to bottom of floor beam. It contains about 1.2 million pounds (600 tons) of structural steel and approximately 55,000 high-strength structural bolts. The arches and cables provide the majority of the structural support for the bridge. The maximum width of the bridge is 43 feet, and it will carry two light rail tracks. The type of high-strength steel used is called “weathering steel.” It will naturally rust to a dark purple-brown color to form a protective oxide coating, thus eliminating the need and expense of painting, now or in the future. The weight of the tracks and ballast crossing the bridge weighs more than all the bridge’s structural steel. The structure can withstand a sustained hurricane force wind of 100 mph. Each of the main pier columns is designed to support 2.7 million pounds. The substructure supporting the span contains 10,686 cubic feet of concrete weighing about 1.6 million pounds.
Arches: The arches angle inward so that the width of the arches at the ends of the bridge is 43 feet while the width of the arches at the crown is 16 feet. Each arch is designed to withstand a compressive force of nearly three million pounds. The hollow arches have full interior access to facilitate construction, future inspections, and maintenance. From extreme cold to extreme hot, the arch span will elongate approximately 3.5 inches. The steel arch span is supported on its own bearings on the two piers adjacent to 6th Avenue and is not directly attached to the approach spans. There are expansion joints at each end of the arch span to compensate for movement caused by temperature changes. The shape of the arch is defined by a mathematical equation which emulates the equation used to describe the force of gravity.
Cables: There are a total of 44 cables on the bridge, approximately 1,950 feet. Each cable is 2 3/8″ in diamter. Each cable has a breaking force of 688,000 lbs (344 tons). If one cable breaks, which is very unlikely, the bridge can still support itself. The cables will be lit with white LED lights, which have a lifespan of 100,000 hours, or about 11 years.
Construction
The arch bridge was constructed and fully assembled at the manufacturer’s site in Oregon. It was then disassembled and transported to Colorado in 34 truck shipments. The transporter consists of two 35′ transport platforms having 8 axles each. Both of these transport trailers contain hydraulic rams used to keep the platform level. The southern end of the arch will travel on guided rollers which are pushed by hydraulic rams, the main driving force. This is the first time in the U.S. that a basket-handled tied arch bridge has been ‘rolled out’ using this method.The bridge will move less than 25 feet per hour across 6th Avenue, taking up to 30 hours to complete the crossing.
The bridge was rolled across 6th Avenue on Saturday, May 1, 2010. All lanes of 6th Avenue were scheduled to be closed between Kipling and Simms/Union in Lakewood from Friday night, April 30th, to Monday morning, May 3rd, 2010. Many intending to view this event were caught off guard by the fact that this effort was completed 30 hours ahead of schedule, with the bridge having been set on its pillars at around 4:00pm Saturday, the 1st of May 2010.

List of old abandoned mansions around the world:
8. Muromtzevo Castle, Russia
The legend of this castle begins in the 1800s when a French and a Russian nobleman started arguing over whose country had the best architecture. After hearing the French nobleman go on and on, the Russian declared that he could easily Build a castle as magnificent as the ones in France. The French man said that if he built this castle he would go to Russia himself to see it and the bet was on. Colonel Vladimir Khrapovitsky went home and built Muromtzevo Castle.
5 years later he invited his French noble friends to his estate to visit his gothic castle. When they arrived they began complimenting him on his new home. “Oh no”, he said. “This is just the stable! The castle is a bit further!” The guests were amazed at the French style chateau complete with gardens and cascades. Khrapovitsky also built two schools and a church for the villagers.
When the Russian Revolution started, Khrapovitsky was forced to flee his castle, and is said to have deceased in poverty. His beautiful creation was plundered and rebuilt in a way the owners would have hardly recognized. It was used as a college, and then a hospital, and then forgotten.
7. Pidhirtsi Castle, Ukraine
Built between 1635 and 1640, Pidhirtsi Castle has survived the trials of war and occupation. Part castle, part fortress, this castle has the reputation for being haunted. In the 18th century one of the owners was said to have ambushed his wife because of his insane jealousy and had her body walled up in the basement. Known as the “Woman in White” she is said to wander the castle. A group of 20 Ukrainian psychics recently agreed that the place was filled with ghosts. Measurements of the electromagnetic field of the castle were off the charts, a pseudo-scientific sign for many that Pidhirtsi is most certainly haunted.
During WWII the castle was taken over and plundered by the Soviets until it was converted into a hospital for people suffering from sickness. A lightning bolt struck the building in 1956, Setting it on fire for three weeks straight, destroying everything left inside. It has now been converted into a museum, telling the story of the struggles of a region.
6. Miranda Castle, Belgium
Also called Chateau de Noisy, this castle in Belgium was Built for French aristocrats fleeing the French Revolution. In 1866, Count Liedekerke-De Beaufort commissioned English architect Edward Milner to design and build them a new home. Even though Milner passed away,
the castle was Completed in 1907 once the clock tower was erected. The Liedekerke-Beaufort family lived in the castle until World War II, when it was occupied by the Germans after the Battle of the Bulge which took place on part of the property.
In 1950, the National Railway Company of Belgium took over the castle and turned it into an orphanage and camp for sick children. This is when it was renamed Chateau de Noisy. It was too expensive to maintain and in 1991, the castle was abandoned. Parts of the structure were heavily damaged in a fire and most of the ceilings have collapsed.
In 2014, the family applied for and was granted permission to demolish Miranda Castle. In 2015, A group of investors intervened to stop the demolition and petitioned to have it included on the Walloon Heritage Conservation List. As of June 2016, the castle is in private hands and is listed as private property. Rumor has it that the family finally agreed to sell, but no one knows who has bought it.
Miranda Castle was used as a filming location for the American series Hannibal. In the show, this Belgian castle is portrayed as Castle Lecter in Lithuania as the ancestral home of everyone’s favorite cannibal.
5. Halcyon Hall, New York
The image of Halcyon Hall is Used by many paranormal investigators to represent haunted places but most people don’t know what or where it is. This rotting relic in Millbrook, New York was originally built as a luxury hotel in 1890 when summer colonies like Newport were popular. H. J. Davison Jr. spent a fortune on the Victorian Queen Anne style building with 5 stories and 200 rooms.
Unfortunately, the resort failed and Davison was forced to sell. It was then purchased in 1907 by May Bennett for her Bennett School for Girls which later became Bennett College. The school had been founded in 1890 in Irvington, NY but needed a larger home.
The Bennett School offered 6 years of education to girls from prominent families in NY.
