The National Transport Authority (NTA) has said they will compensate homeowners affected by their plans.
The transport authority confirmed that more than a thousand households in Dublin will lose part of their gardens to facilitate room for new routes that may reduce journey times by 50%.
Routes in suburbs such as Bray, Lucan and Swords will see the construction of 230km of bus lanes and an extra 200km of cycle lanes to decrease journey times for commuters.
The land needed to execute the NTA's plans will be subjected to a Compulsory Purchase Order to make sure the upcoming infrastructure can be implemented.
The plan, to be rolled out by the National Transport Authority, is planned for completion by 2027 and is expected to cost €2 billion.
The routes to be affected by the NTA's plans include:
1 Clongriffin to city centre
2 Swords to city centre
3 Ballymun to city centre
4 Finglas to Phibsborough
5 Blanchardstown to city centre
6 Lucan to city centre
7 Liffey Valley to city centre
8 Clondalkin to Drimnagh
9 Greenhills to city centre
10 Kimmage to city centre
11 Tallaght to Terenure
12 Rathfarnham to city centre
13 Bray to city centre
14 UCD/Ballsbridge to city centre
15 Blackrock to Merrion
