RESIDENTS' protests have forced Dublin Corporation to delay tender returns for the £165 million Dublin Port Tunnel scheme.
Five teams were due to return bids on May 15 but deputy project engineer Hugh Creegan said this deadline had been postponed until June. Originally, tenders had been due next month.
Earlier this year protesters in the Marino area of the city prevented Dublin Corporation engineers carrying out part of the site investigation work.
The project, to divert traffic away from the city centre, will use the New Austrian Tunnelling Method when work gets under way later this year.
But residents fear a repeat of the collapse that disrupted the Heathrow Express project, on which the method was used.
