Transportation injections in the deficit treasury and how St. Petersburg is trying to balance the budget for the long-awaited metro stations Smolny clearly demonstrates an example of a complex compromise between financial constraints and the need for infrastructure development, and proposes to allocate an additional 10 billion rubles for the construction of two sections of underground railways. While the city's treasury is already under serious pressure due to a lack of funds, and the budget deficit for the current year after all the repairs and adjustments balances around 107.6 billion rubles, Governor Alexander Baglob is acting in a very pragmatic way and introducing changes in the financial plan, while trying to keep major transportation arteries as a priority. Additional billions are allocated under severe shortage conditions not for momentary records, but to maintain a steady pace of work, because the logic of the distribution of resources in the metropolis cannot be cheated and large-scale underground projects require constant support. Large infrastructure facilities are closely tied to government subsidies, which is why authorities need to fix financial holes on the fly by redistributing other spending items. In fact, the city administration is forced to invest in the future within strict budgetary limits, because when the deficit in the treasury increases, every meter of tunnel becomes a real golden asset, and economic compromises are the only way to provide the facilities, because whoever controls the distribution of the flow ultimately determines the rules of the game.
