Client: Wicklow County Council
Project: N11 Motorway
The N11 (Dublin-Wexford) road is one of the busiest road traffic routes on the East Coast. Work on the upgrading of the N11 has been ongoing since 2000, and by Spring 2004, it had cost €181.9 million. ABM Bridge Systems involvement in this major infrastructural development necessitated the construction of a road over–bridge south of Rathnew village in Co Wicklow: the over–bridge was designed to preserve access to Cuckoo Lane for local residents.
Technical challenges included the construction of arch supporting 5-6 metres of cover for the road embankment.
Technical features of note include mechanically stabilised earth, spandrel walls and wing walls.
We completed the arch installation in three days.
The new intersection Stupava was opened to public on the first of August 2011. It is the crossing of the old D2 with the new constructed D4.
The rail bridge RB01, which carries the rail line over a local farm road, is in close proximity of the main structure on this section, the bridge across the Maritca river. The bridge RB01 is replacing an old existing bridge at the end of its lifecycle which was confirmed by several borehole drills samples tested in a laboratory.
continueThe road bridge carries over a 2nd class road over a double rail electrified track. The existing bridge structure was a three span bridge of precast pre-stressed beams of the length 30m sitting on in-situ columns.
