You don’t even have to dig!
It turns out that under the Moscow Avenue there is a tunnel that can be used to improve the transport situation. Petersburg, of course, is not Rome and not Paris, under which, as they say, everything is exposed by catacombs. But in our city there are underground structures that units know about. For example, near Moskovsky Prospekt, at the Elektro metro station, there is a tunnel of a four -meter width, according to which it is quite possible to allow vehicles.
