Dubki horse-iron road

The production оf the Sestroretsk armory was originally transported into Saint Petersburg on the coast, on the supplies. But the road to the capital existing at that time was inconvenient, since it lay along the coast on quicksands and lowlands, by the periodically submerged waters of Gulf of Finland. Therefore seagoing scows later began to be used. In 1847 a horse-drawn tramroad was built from the plant to the Dubkovsky pier on the Gulf of Finland. In the diagram this road is not shown, but it passed along the axis of street to the centre of the map. The opening and the place for pier are designated on the map.
