Jack Lynch Tunnel
The Jack Lynch tunnel is an immersed tube tunnel and an integral part of the southern ring road in Cork, Ireland. The tunnel has 2 cells each with 2 traffic lanes and 2 footpaths and a central bore for use in emergencies. The tunnel is controlled by a closed circuit tv, traffic control and supervisory control and data acquisition (scada) system. External photocells linked to the scada system provide a level of tunnel lighting most compatible with ambient light levels outside. We completed the electrical services installation on the initial construction project and have subsequently been awarded maintenance service contracts.
