Clay Farm, Leopardstown

Great to see the bridge at Clay Farm in operation. Our drone footage shows this 100-metre long reinforced concrete bridge, designed by DBFL, providing a vital spine through Clay Farm, crossing the valley and linking both phases of this residential development where DBFL are also acting as Civil, Structural and Transportation consultants.

At the foothills of the Dublin mountains, Clay Farm development numbers 1,440 units in a mix of houses and apartments, with the final stage due for completion in 2024.
 

It was proposed to construct the bridge over a stream in the valley that is susceptible to flooding. The bridge consists of four spans, each of approximately 25m in length. The bridge is a composite concrete structure consisting of an in-situ reinforced concrete deck on prestressed precast concrete bridge beams on an in-situ reinforced concrete sub-structure.
 

The bridge structure is approximately 18m wide overall and consists of a carriageway, two cycle tracks and two footpaths. It provides passage for all public utility services from one phase of the development to the other. The precast concrete beams hold both the gas and water mains, whilst the public utilities services (ESB, public lighting, telecoms, etc.) are held above the in-situ deck in the footpaths.
 

Running under the bridge is a 700m long footpath along the riverbanks and rich greenery which links to the Cruagh Wood Greenway for pedestrian access to nearby Luas and bus facilities.
 

The bridge has been nominated in the Infrastructural category of this year’s Irish Concrete Society Awards
