The cabinet will approve the BusConnects preliminary plan this morning, that will transform Dublin's bus network.
It will allow planning applications to be submitted for the main bus corridors and the development of next-generation ticketing like mobile apps.
The programme includes 230km of bus corridors, increasing services by 25 per cent.
Construction will be carried out in three phases to reduce the impact on commuters.
The first will start in 2024 and comprise routes from Clongriffin, Blanchardstown, Tallaght and Bray to Dublin city centre.
Work is likely to last until at least 2030.
