Directly between St Isaac's Cathedral and the City Hall building there is a bridge, as wide as the adjacent Isaakievskaya Square, that is rather tricky to see. At 319 feet 2 inches (97.3 meters) the so-called Blue Bridge (Siniy Most ) is the widest bridge in the world. However, to the dismay of the people of St. Petersburg the Blue Bridge was not accepted as the Widest Bridge in the World by the Guinness Book of Records. The reason for this is, unfortunately, unknown but if you find a wider bridge elsewhere in the world please let us know!
The Blue Bridge was designed by the architect V.I. Geste and built of cast iron in 1818. Between 1842 and 1844 it was reconstructed and widened to span a distance of 319 feet 2 inches. The name "Blue Bridge" originated from the tradition of color-coding downtown bridges. Hence the lower part of the Blue Bridge is still painted blue.
St. Petersburg bridges: we boast more bridges than anywhere else!
