Public buses in Sofia

The Sofia public bus system forms part of the public transport network of Sofia, the capital city of Bulgaria.
In operation since 1935, the system presently comprises 98 routes.

History

The public bus transport in Sofia developed relatively late compared to the other types of transport in the city. The first operational line was opened on 20 April 1935. Soon after that six more lines were opened, bringing the total network length to 23 km.
During the communist era, the bus fleet consisted mainly of Ikarus and Bulgarian-made Chavdar buses. After the political changes in 1989, however, the fleet has gradually been modernised.

Night bus service

Sofia has a night bus service. It was launched by Sofia Urban Mobility Center on an experimental basis from 7 April 2018 until 31 December 2018. Tickets for the night bus can be obtained solely from conductors on the bus, and not from the driver, machines or other public transport ticket sale points. Tickets for the night bus cost 2 leva compared to the daytime price of 1.60 leva. Knyaz Alexander Square is used as the site of a transfer location where all night bus lines meet and passengers can switch lines.
Four routes are included and operated from 23:30 until 04:20 at intervals of 1 hour.
The night bus service was closed due to COVID-19. In November of 2023, the N1 and N2 lines were re-established, with the rest of the network being brought back in December of the same year, but with changed routes:

Line	Route	Garage
N1	Lyulin 1, 2 – Mladost 4	Malashevtsi
N2	Obelya – Students' Town	Malashevtsi
N3	Ovcha Kupel 2 – Levski G	Zemlyane
N4	Gotse Delchev – Druzhba 2	Druzhba
