Pevchesky Bridge
One of the St. Petersburg bridges that are wide enough to support a whole square, Pevchesky Bridge crosses the Moika River close to Palace Square and the Choral Chapel, from which it takes its name. Built in 1839-1840 by engineer E.A. Adam to replace a wooden bridge that had stood only five years, the Pevchesky Bridge is 72 meters wide, and consists of a single arched span of cast iron resting on rubble abutments faced with granite. The bridge's railings, of openwork cast iron, are particularly impressive.
