Transport

Main article: Transport in Dublin Road The M50 motorway surrounding Dublin.

The road network in Ireland is primarily focused on Dublin. The M50 motorway, a semi-ring road which runs around the south, west and north of the city, connects important national primary routes to the rest of the country. In 2008, the West-Link toll bridge was replaced by the eFlow barrier-free tolling system, with a three-tiered charge system based on electronic tags and car pre-registration. The toll is currently €2 for vehicles with a pre-paid tag, €2.50 for vehicles whose number plates have been registered with eFlow, and €3 for unregistered vehicles.

The first phase of a proposed eastern bypass for the city is the Dublin Port Tunnel, which officially opened in 2006 to mainly cater for heavy vehicles. The tunnel connects Dublin Port and the M1 motorway close to Dublin Airport. The city is also surrounded by an inner and outer orbital route. The inner orbital route runs approximately around the heart of the Georgian city and the outer orbital route runs primarily along the natural circle formed by Dublin's two canals, the Grand Canal and the Royal Canal, as well as the North and South Circular Roads.

Dublin is served by an extensive network of nearly 200 bus routes which serve all areas of the city and suburbs. The majority of these are controlled by Dublin Bus, but a number of smaller companies also operate. Fares are generally calculated on a stage system based on distance travelled. There are several different levels of fares, which apply on most services. The Bus Arrival Information Service is being rolled out which provides bus stops with information on the distance of buses based on GPS positions of the buses.

Heuston and Connolly stations are the two main railway stations in Dublin. Operated by Iarnród Éireann, the Dublin Suburban Rail network consists of five railway lines serving the Greater Dublin Area and commuter towns such as Drogheda and Dundalk in County Louth. One of these lines is the electrified Dublin Area Rapid Transit (DART) line, which runs primarily along the coast of Dublin, from Malahide and Howth southwards as far as Greystones in County Wicklow. Commuter rail operates on the other four lines using Irish Rail diesel multiple units.

The Luas is a two-line light rail or tram network which has been operated in Dublin by Veolia Transport since 2004. The network consists of two routes; the Red Line links Dublin with the nearby town of Tallaght to the south west and the Green Line connects a variety of suburbs to the south of the city. Together they comprise a total 54 stations and 38.2 kilometres (23.7 mi) of track. A decision on whether to expand the Luas system will be made in September 2011, when a new national development plan is to be published. Proposed multi-million euro projects such as the Dublin Metro and the DART Underground will also be considered in light of the current difficult economic climate.

Airport

Dublin Airport is operated by the Dublin Airport Authority and is located north of Dublin City in the administrative county of Fingal. It is the headquarters of Ireland's flag carrier Aer Lingus, low-cost carrier Ryanair and regional airlines Aer Arann and CityJet. The airport offers an extensive short and medium haul network, as well as domestic services to many regional airports in Ireland. There are also extensive Long Haul services to the United States, Canada and the Middle East. Dublin Airport is the busiest airport in Ireland, followed by Cork and Shannon. Construction of a second terminal began in 2007 and was officially opened on 19 November 2010.

Dublin Airport currently ranks as the 25th busiest airport in Europe recording nearly 19 million passengers during 2011.

Cycling

Dublin City Council began installing cycle lanes and tracks throughout the city in the 1990s, and as of 2012 the city has over 200 kilometres (120 mi) of specific on- and off-road tracks for cyclists. In 2011, the city was ranked 9th of major world cities on the Copenhagenize Index of Bicycle-Friendly Cities.

Dublinbikes is a self-service bicycle rental scheme which has been in operation in Dublin since 2009. Sponsored by JCDecaux, the scheme consists of 550 French-made unisex bicycles stationed at 44 terminals throughout the city centre. Users must make a subscription for either an annual Long Term Hire Card costing €10 or a 3 Day Ticket costing €2. The first 30 minutes of use is free, but after that a service charge depending on the extra length of use applies. Dublinbikes now has over 58,000 subscribers and there are plans to dramatically expand the service across the city and its suburbs to provide for up to 5,000 bicycles and approximately 300 terminals.
