Road Network

Dublin is also the main hub of the country’s road network. The M50 motorway, a semi-ring road runs around the south, west and north of the city, connecting the most important national primary routes in the State that fan out from the capital to the regions. A toll of 1.80 applies on what is called the West-Link, two adjacent concrete bridges that tower high above the River Liffey near the village of Lucan. Construction of the M50 took almost 20 years, with the final section opening in June 2005. A court case regarding the destruction of medieval ruins at Carrickmines Castle delayed the final completion of the route. The M50 currently has two traffic lanes going either direction but plans are afoot to increase that to three. The National Roads Authority also intends to increase capacity at many of the motorway’s busiest junctions by building triple-grade interchanges instead.

To complete the ring road, an eastern bypass is also proposed for the city of Dublin. The first half of this project is currently under construction, the Dublin Port Tunnel. It is scheduled to open in early 2006 and will mainly cater for heavy vehicles. When finished, Dublin City Council hopes to ban all unnecessary trucks and lorries from the city quays. The second half of the project would involve another tunnelling project, linking Dublin Port to the road network on the southside of the city. Plans for this have never been formalised.

The capital is also surrounded by what have been termed by Dublin City Council as an inner and outer orbital route. The inner orbital route runs roughly around the heart of the Georgian city from St. Stephen’s Green to Mountjoy Square and from the King’s Inns to St Patrick’s Cathedral. The outer orbital route runs largely 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.
