Pictures with a difference

There are some great photography which surely worth a mention which are taken by me and others.I try to narrate stories behind each photography and their importance.I heavily borrowed from great photographers from National Geographic,Discovery and Flickr.As I am not a proffessional photographer' I HEAVILY dependant on others creative works.Surely, I mentioned their names where ever required.Also being a Civil Engineer I tried to mention some great works of construction through out the world with a mention of importance of land marks like the BIG DIG in US,The Delhi METRO in India,The Qingzang Railway by the Chinese etc.

For others photo I mentioned their names and copyright permissions for not violating by using them.

Quingzang railway is a high-altitude railway that connects Xining, Qinghai Province, to Lhasa, Tibet Autonomous Region, in China.The total length of Qingzang railway is 1956 km. The 1142 km section between Golmud and Lhasa was inaugurated on 1 July 2006 by president Hu Jintao. The line includes the Tanggula Pass, which, at 5,072 m (16,640 feet) above sea level, is the world's highest rail track. The 1,338 m Fenghuoshan tunnel is the highest rail tunnel in the world at 4,905 m above sea level. The 4,010-m Guanjiao tunnel is the longest tunnel from Xining to Golmod and the 3,345-m Yangbajing tunel is the longest tunnel from Golmod to Lhasa. More than 960 km, or over 80% of the Golmud-Lasa section, is at an altitude of more than 4,000 m. There are 675 bridges, totalling 159.88 km, and about 550 km of the railway is laid on permafrost.

The Big Dig is the unofficial name of the Central Artery/Tunnel Project (CA/T), a megaproject that rerouted the Central Artery (Interstate 93), the chief highway through the heart of Boston, into a 3.5 mile (5.6 km) tunnel under the city. The project also included the construction of the Ted Williams Tunnel (extending Interstate 90 to Logan International Airport), the Leonard P.Zakim Bunker Hill Memorial Bridge over the Charles River, and the Rose Kennedy Greenway in the space vacated by the previous I-93 elevated roadway. Initially, the plan was also to include a rail connection between Boston's two major train terminals. The project concluded on December 31st 2007, when the partnership between program manager Bechtel/Parsons Brinckerhoff and the Massachusetts Turnpike Authority ended.
