Bridge of the Future
Though not in Moscow, a bridge over the Kerch Strait has been an ambition by many Russian politicians since after WWII, especially Vladamir Putin, and this dream is coming into fruition - the Crimean Bridge is expected to be handle cars by December 2018, according to an article on this news site. Perhaps the impressive track record that Moscow bridges have led the way to even humoring the idea of building a twelve mile (19 kilometer) bridge from Russia to Crimea.
However, many engineers think that the bridge will not be structurally sound. In fact, according to a Popular Mechanics article, there is a channel underneath where the bridge is supposed to go that makes it difficult to have a strong foundation. Other worries such as vulnerability to volcanoes and earthquakes are floating around. Despite the anticipation of the bridge, the slave-like conditions for the workers, and the push for it to be finished in the next few years, the bridge may run into its fair share of Achille's heels.
This point goes to another grander one about cities and expectations. Once a city has a history of success in one arena or another, it makes it hard to violate either maintaining or improving upon those precedents. Clearly, we have seen that Moscow is a bastion of beautiful bridges, but what happens when they try to out-do anything they've done before? Time will tell.
