Building of the vestibule included a reconstruction of the whole square, that feature a long subway under the square's square's eastern and southern perimeter: two entrances on the corner of the FSB headquarters and a service drive along its western facade, two on the corner of FSB's computing centre (Lubyasky drive and Myasnitskaya street), a further two to the small garden before the Polytechnical Museum the containing the Solovetsky Stone memorial (Lubyansky drive and Novaya square) and a final two right in front of the original entrance. From the new subway, a small passageway was added linking the old vestibule underground. It is thus possible to circumvent the whole square underground and walk from one vestibule to the other without descending to the platforms.
