SOFIA — Proposals by civic group “Spasi Sofia” to reorganize several of the capital’s public transport lines have cleared a key hurdle in the municipal Transport Committee and are now headed for a final vote in the City Council this Thursday.
The reforms aim to improve efficiency, accessibility, and environmental sustainability across the city’s public transport network. Among the most significant changes is the planned extension of night bus line H4 to Sofia Airport.
If approved, the service will begin running to both airport terminals and the Druzhba residential area starting July 15. The expansion is expected to support the estimated 22,000 nighttime passengers traveling through the airport and cater to employees in the nearby logistics zone who work night shifts.
“This move ensures round-the-clock public transport to one of Sofia’s most important transportation hubs,” said Gergin Borissov of “Spasi Sofia.”
He noted that the extended H4 line will not require additional drivers or buses, maintaining the current 2 leva fare and inclusion in existing annual passes. The extension also aligns with Sofia Airport’s carbon reduction goals.
In another major shift, bus line 184—introduced in 2017 to connect the city center with Terminal 1—will be merged with the more frequent line 84. This streamlining is based on changes in air traffic patterns, with Terminal 2 now handling three times more passengers than Terminal 1.
The merger is expected to create a simpler, more reliable service with consistent 12-minute intervals throughout the day, benefiting Druzhba residents and air travelers alike.
Trolleybus routes will also see adjustments. Trolleybus 6 is set to be extended to the Spartak swimming pool, with a rerouting through Opalchenska Street and the Pette Kosheta intersection.
Additionally, the temporary diversion of trolleybus 7—currently serving the Gotse Delchev area, Sofia University, and Stochna Station—will be made permanent.
This decision ensures the continuation of a popular route even after roadworks on Opalchenska Street are completed.
“These proposals preserve important connections while also improving network coverage and usability,” said Andrey Zografski, deputy chair of the Transport Committee. “They strengthen links between central Sofia and key neighborhoods like Lyulin, Sveta Troitsa, and Lozenets.”
Supporters of the changes believe the plan reflects a pragmatic approach to improving urban mobility. Borissov emphasized that the proposals are based on real passenger needs and are in line with broader urban development goals, including reducing car dependency and emissions.
The City Council is set to vote on the package this Thursday. If approved, the changes will mark one of the most comprehensive public transport reforms in recent years.
“Spasi Sofia” hopes the initiative will encourage more residents to switch to public transport, contributing to a more livable and environmentally conscious capital.
