Members of the media walk on the deck of the newly constructed eastern span of the San Francisco-Oakland Bay Bridge during a media tour of the self-anchored suspension span tower on August 29 in Oakland, California. Construction crews have erected twelve foot wide catwalks that connect to the San Francisco-Oakland Bay Bridge self-anchored suspension span's tower and crews will begin to lay the nearly one mile of main cable beginning in early 2012. The bridge has been under construction since 2002 with an estimated price tag of $6.3 billion and will have the world's tallest self-anchored suspension (SAS) tower once completed.

A little Kyrgyz girl combs her hair while standing in a plastic basin after bathing in the village of Dordoi, some 20 km from the capital of Bishkek, Kyrgyzstan, on Nov. 28. Local resident Arstan-Baike keeps this bath as a small family business, offering local residents a bath for one dollar per person. The village located near the biggest retail market in Central Asia lacks infrastructure and social facilities like schools, hospitals and baths. Arstan-Baike stokes his stove with used tires because of the wood shortage in the area.
