Semyonovsky Bridge or Semenovsky Bridge (Russian: 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).
