The National Transport Authority (NTA) said the new bus network for Dublin will increase bus services by 23%.

The new bus network has been unveiled based on eight new super frequency spines and 12 orbital route, which will be introduced on a phased basis starting the new year subject to government funding.

The final design follows three rounds of public consultation involving a total of 72,000 submissions.

It is based on the cross city spines lettered A to H arriving every five to 15 minutes connecting with 12 orbital routes and a large number of local routes.

For instance the A route would connect Swords on the Northside to Terenure on the Southside through the city centre with branches connecting areas near each terminus.

For example, the  A1 would go from Beaumont to Knocklyon.

But the first routes to open next year are expected to be the H to Howth, followed by the C to Lucan.

The orbital routes would include the O route travelling around the city centre on the North and South Circular Roads from Heuston Station.

The Minister for Climate Action, Communication Networks and Transport, Eamon Ryan, said Dublin is a growing city that needs an efficient bus services.

"The last six months have been very challenging for everyone in Dublin and across Ireland. Bus services have provided an essential frontline service for the public and city during this time and the new Dublin Area bus network will allow the service grow to meet people's needs as the city recovers."

The original plan by an international transport consultant led to a large number of objections.

It would have led to the loss of direct connections to the city centre for areas like Rush, Howth and Dunboyne which have rail services. Commuters in those areas travelling by bus would instead interconnect with 'hubs'.

There were also a large number of complaints about the loss of local connections to schools, hospitals and to Dublin Airport for workers in north Dublin.

The new design by the NTA means towns like Rush and Dunboyne will get direct connections at peak commute times while an extra spine - H - was created to service Howth.

A large number of local routes have been altered following particular concerns including those of residents in Crumlin, Rathmines and Marino.

There were a further 39 alterations to routes following the second round of consultation.

The NTA said the new design will mean the number of people living within 400 metres of a frequent bus service to the city centre will increase by 16% to 925,000.

The authority does concede that local routes will require planning on behalf of the commuter.

It said: " the outbound journeys (from the City Centre), particularly at off peak times, will require careful coordination of timetables to manage interchange from higher frequency to lower frequency bus services."

The new network will include a number of routes that will have 24-hours operations arriving at 30 minute intervals for the same fare.

The implementation of the overall design will be in 11 phases with each spine or half a spine route being introduced along with its connecting local routes.

The design is a separate part of Bus Connects from the Core Bus Corridor project which involves the redesign of roads and using part of front gardens.

This is due for another round of public consultation later this year.
