The first new Dublin bus route redesigned as part of the Bus Connects programme will come into service this weekend.

Route H will connect Howth, Malahide and Portmarnock with a high frequency service to the city centre.

Route H is the first of eight main spines, which will connect with 12 orbital routes around the network.

The original route redesign provoked 70,000 submissions from commuters concerned about loss of minor routes and possible privatisation,

There have been many changes to that vision and Howth was originally not planned to have a spine connection at all.

The H route's main centre will be Raheny with buses running every eight minutes there and even more during peak demand.

Less frequent branches - H1, H2 and H3 - will travel to Baldoyle, Malahide and Howth.

A new 'radial route' No 6 will run every 60 minutes to connect the Western side of Howth with Route H and the city centre.

The other seven routes are all cross city and the next one to start will be C, running from Sandymount to Leixlip and Maynooth.

Overall, the National Transport Authority said Bus Connects will mean a 23% increase in services.
