Much of material used to build road comes from rock quarried on route

MUCH of the material used in the construction of the Tralee bypass is coming from the route of the bypass itself.

As well as a massive construction operation, which is using local subcontractors wherever possible, BAM have essentially constructed a mobile factory, using rock quarried from along the route, to make the tarmac and concrete based products needed to build the road.

In the course of building the bypass, BAM has already used 100 tonnes of explosive to blast and quarry some 300,000 tones of rock, mainly limestone, from locations along the route.

Management at BAM said the use of rock from the bypass route had saved the company the need to bring in around 16,000 truckloads of rock to the site from other areas, the transport of which could have had a massive impact of traffic in the area around the extensive bypass site.

The blasting process itself is surrounded in red tape governing health, safety and security.

Whenever blasting is carried out a member of the Kerry Gardaí is required to be on site to monitor the arrival, placement, and actual detonation of all explosives.

The company also monitors the effect of explosives, especially vibrations caused by the detonations, on houses and properties close to the blasting sites.
