The Dublin Tunnel (Irish: Tollán Bhaile Átha Cliath), originally and still commonly known as the Port Tunnel, is a road traffic tunnel in Dublin, Ireland, that forms part of the M50 motorway.
The twin tunnels form a two-lane dual carriageway connecting Dublin Port, which lies to the east of central Dublin, and the M50 motorway at junction 2, close to Dublin Airport. The tunnels are 4.5 km (2.8 mi) in length and total project length of 5.6 km (3.5 mi). It had a final cost of approximately €752 million.
The tunnel was officially opened on 20 December 2006; it was initially only open to HGVs.[1] It was opened to all traffic on 28 January 2007.[2]
