The Dubki horse-iron road was built to serve the armory at Sestroretsk Russia. The production оf the Sestroretsk armory was originally transported to Saint Petersburg along the coast by road. But the road to the capital existing at that time was inconvenient since it lay along the coast on quicksands and lowlands which were periodically submerged by the waters of the Gulf of Finland. Therefore seagoing scows (barges) later began to be used.
