Semyonovsky Bridge or Semenovsky Bridge (ru|Семёновский Мост) is a bridge across the Fontanka River in Saint Petersburg, Russia. It carries the Gorokhovaya Street. It was opened in 1733 as a wooden bridge and became one of the first bridges across Fontanka. The bridge was rebuilt in stone in 1788, presumably, by Jean-Rodolphe Perronet). In 1857 the dilapidated pillars were rebuilt by engineer Fyodor Enrold. Almost a century later, in 1949, the pillars and main beams were reinstalled in metal.[1]
The bridge took its name from the Semenovsky Imperial Guard regiment barracks located nearby.[2]
The area is home to many sightseeing boats going to the Winter Palace, Peter and Paul Fortress, Summer Garden, and the Church of the Savior on Blood.
