Photo 3761-22: A rare view underneath the Visconti Bridge...a suburb of St.Petersburg, Russia

A rare view underneath the Visconti Bridge, revealing its dual function as a dam (plotina). The metal sluice gate system shown here is what controls the water level of the Slavyanka River. By regulating the flow through these gates, the park engineers could artificially raise the water level upstream, creating the wide, mirror-like "lake" seen in the previous images. Pavlovsk, a suburb of St.Petersburg, Russia
