Deemed one of the busiest stretches of road in Ireland, the M7 was the next stage for S Evans & Sons to showcase their skillset and capabilities! Navigating from Limerick to Dublin, the M7 has more than 80,000 cars pass over its tarmac each day; selecting the finest demolition contractor for the project was key. The results showed that S Evans & Sons really were the right choice.

The project was carried out 36 hours ahead of schedule, with zero incidents. The demolition was carried out safely and efficiently thanks to careful planning and preparation by our project team, this coupled with a dedicated and meticulous site team ensured the demolition was a resounding success.

Below is a timeline of highlights from the demolition works that was carried out in record time.
