A section of a major new motorway linking Limerick Southern Ring Road with the existing Nenagh bypass in Ireland will open in October, following the completion of repair works.

The €425m ($542.59m) project involves 28km of dual carriageway, which was due to be completed last year but was delayed after a section of the M7 collapsed into a bog.

Thousands of steel-reinforced concrete piles were initially driven into the bog to support the road, and a concrete and steel bridge has been constructed to provide a stable base for the road.

About 25km of the project is already open to traffic while the last section, from Nenagh to Castletown, is due for completion in November.

The project is being delivered by Irish-based Bothar Hibernian, according to The Irish Times.
