The authorities running the Dublin Port Tunnel are conducting an investigation to see if the recent flooding in North Dublin could affect the €448m project. A spokesman said that they hoped to have an understanding by Monday.

Meanwhile, unofficial strike action at Dublin's Port Tunnel has been averted following all-day talks. Representatives from SIPTU and the Construction Industry Federation have agreed to meet later this week over disputed work practices, which led to 130 workers mounting unofficial pickets yesterday.
