Six Flags New Orleans, also abbreviated to SFNO, is an abandoned theme park in New Orleans, Louisiana, that has been closed since just before Hurricane Katrina struck in August 2005 and is currently owned by the city of New Orleans. Six Flags had previously owned the park since March 2002, but after assessing the devastation caused by Hurricane Katrina and the related exorbitant expenses of repairing the damage, sought to terminate their 75-year lease with the city, beginning in July 2006 and finally succeeding in September 2009. The park is located in Eastern New Orleans, in the Ninth Ward of the city, off Interstate 10. Despite various announced plans to redevelop the site, as of 2014, it is still an abandoned amusement park in extremely poor condition. It is a well-known urban exploration destination.

An older model Ford Mustang sits on cinder blocks with missing wheels near an abandoned apartment building in Detroit, Michigan January 7, 2015. Detroit, also known as the Motor City, is the historic hub of automobile manufacturing in the United States. A federal judge in December 2013 formally declared the city bankrupt but it won court approval to exit bankruptcy last November. Once the proud symbol of U.S. industrial strength, Detroit fell on hard times after decades of population loss, rampant debt and financial mismanagement left it struggling to provide basic services to residents.

A new LED light fixture is secured to the side of a lift as crews replace existing street lights August 1, 2011 in Las Vegas, Nevada. The new energy-efficient fixtures are expected to reduce the city's annual electricity use by eight million kilowatt hours, saving about USD 400,000. The city estimates the LEDs will last about 15 years, nine years longer than the current lights. Funding for the project comes from federal energy conservation bonds and an American Recovery & Reinvestment Act grant. The city plans to replace all of its 50,000 streetlights after more funding is secured. (Photo by Ethan Miller/Getty Images)
