Mysteries of the Abandoned - Season 1 Episode 3

Exploring various historical sites, who built them and why they became abandoned…the Kinzua Viaduct from Pennsylvania to the Great Lakes region, built by the Phoenix Steel Company in 1882 and brought down 44 years after it becomes a tourist attraction by an F-1 tornado which topples over half the bridge in 2003; Chernobyl in Pripryat, Ukraine built in 1970 by the USSR a restricted, technologically advanced city that could house around 50,000 people, which fell to disaster on 26 April 1986 when reactor 4 melts down and the residents are only evacuated after 30 hours, never to return; 52 Tunnel Road, Monte Pasubio Italy, carved 4 miles long at 6,600 feet elevation through the top of the Italian alps in 1916, in only 9 months during brutal winter weather, in an attempt to stop the WWI troops from invading through the mountains to Venice, which costs hundreds of lives in the making but at completion accomplishes its goal, only to be abandoned by the Italian army in 1936 after several major accidents and deaths, though it is still open to the public who dare to traverse the rubble; in the shallow waters of Mallows Bay, Maryland on the edge of the Potomac River, lie the remains of over 200 wooden steamships, some up to 300 feet in length, built by 87 companies in 1917 to ship supplies of munitions to the Allies in Europe during WWI, never to be used for their purpose because of budgetary, engineering and time constraints, which now form part of a huge nature reserve providing refuge for ospreys and water fowl.
