The closure is taking place due to the ongoing project on the upgrading of the railway line between Prague Main Train Station and Prague Hostivař Station.

Because of the preference of public transport buses on the detour route, the underpass in V Korytech Street (between U Trati Street and the Radošovická tram loop) will also be closed for private vehicles in the direction from Zahradní Město to Strašnice. Private vehicles will be directed to take a detour via the roads Jižní Spojka – Černokostelecká, or Chodovská – Bohdalecká.
