Many arguments were advanced against the construction of an underground road. The "city fathers" stated that the excavation works would "violate the amenities and respectability of the city"; the landlords affirmed that underground traffic would undermine the foundations of the buildings; the merchants feared that "the open excavations would interfere with normal trade"; but the most violent adversaries of the novelty, the clergy, insisted that "the underground passages running near church buildings would detract from their dignity". Thus all the projects for the construction of an underground passage in Saint Petersburg, and later in Petrograd, remained on paper.
