A high-powered executive body will be established within months to drive forward the new multi-billion euro transport plan in the capital, a senior minister said.

The biggest infrastructure plan in Irish history was announced today with a €34.4bn upgrade package for roads, railways and metro lines over the next 10 years.

Transport Minister Seamus Brennan’s plans to alter the LUAS line around Dublin’s Red Cow roundabout could cost an extra €20m and delay the project by nine months, according to reports this morning.
