Blue Bridge
The widest bridge in St. Petersburg, the Blue Bridge can easily pass unnoticed, as it carries much of St. Isaac's Square on its 97.3-meter back. The first section of the present bridge, a single iron span on stone supports designed by V. Geste, was erected in 1805. In 1841, the bridge was more than doubled in size to its present width. In the 19th century, the bridges along the Moika River were color-coded, and the Blue Bridge is one of four to maintain this tradition. Its elegant cast iron railings are painted a distinctive shade of sky blue.
