In the case of a truss bridge, a post-tensioned slab bridge, or a box girder bridge the sections are often floated to the bridge and then lifted into place by cranes on barges or cranes sitting over piers.
The very good reason why the word communism is so commonly associated with these revolutionary, anti-liberal, anti-democratic Marxists is that political parties with communist in the name were pretty much invariably of that bent throughout the 20th century, whereas parties called socialist or social democrat or labor varied enormously in ideology.
Organized anti-communism developed in reaction to the rise of communism, especially after the 1917 October Revolution in Russia and reaching global dimensions during the Cold War. Most anti-communists reject the concept of historical materialism, which is a central idea in Marxism.nti-communism remained a theme in far right politics after the war. For example, in the US, Frank L. Britton, editor of The American Nationalist published a book, Behind Communism, in 1952 which disseminated the myth that Communism was a Jewish conspiracy originating in Palestine.
