Fossa Way Cycling route is a new amenity that begins on Mission Road just off Killarney Town Centre and enters the national park adjacent to St. Mary’s Cathedral.  The cycle lane travels for 5km through the park where it offers magnificent views of the Killarney lakes and mountains, along its route it travels adjacent to the Dennagh River where we constructed a bridge to link up with the Fossa Road.

 

As this project was in a sensitive area we worked closely with the National Park and Killarney Town Council as Killarney National Park contains many features of national and international importance such as native oakwoods, yew woods together with an abundance of evergreen trees and shrubs.  The project involved tree felling, 25,000m2 site clearance, large quantity of bulk fill, landscaping, 15,000m2 surface dressing.  Strict environmental procedures were put in place for machinery entering the national park.

Camden Fort is a national monument comprising primarily of 19th century military fortification on the site of a 17th century fort.  It is internationally recognized as being one of the finest remaining examples of costal artillery fort in the world.  The fort dates back to 1550 on 45 acres with 65% underground.  The project involved 800 meters of main drainage, rising main and underground services through an average depth of 1.8m.

 

These works began on the public road outside the fort and carried through the fort where a large number of 18th, 19th and 20th century culverts were discovered during the works.  The most challenging part of the project was on the costal edge of the fort where the drainage was on the steepest slope of the site with very restricted access.  All works were carried out in a live operational environment.
