N25 New Ross Bypass
This project involves the design, construction, financing, operation, and maintenance of approximately 13.6 km of new dual carriageway (N25 & N30 routes) and 1.2 km of new/upgraded single carriageway (New Ross N30) route and various structures (junctions and road bridges), the most notable of which is the 887 m River Barrow crossing, a three tower extradosed bridge. The bridge will be the longest of its type in the world.Finde mehr heraus
SPV General Manager Larry Mackey outlines the background to the M11 project.
„The N25 is a strategic link in the national road network connecting Cork and Rosslare and forms part of the Atlantic Road Corridor route joining Waterford in the south-east to Letterkenny in the north-west by dual carriageway or motorway. The N25 is also part of the Trans-European Network-Transport (TEN-T).
„The New Ross bypass scheme begins at Glenmore in County Kilkenny and crosses over the River Barrow via an extrados bridge at Pink Point in County Kilkenny and Stokestown in County Wexford.
„It then continues in an easterly direction where the bypass intersects with the R733 in Landscape and in a northeasterly direction to connect to the N25 at Ballymacar Bridge. From there the bypass route continues to the northeast finishing at the N30, at a point to the east of Corcoran’s Cross.“Finde mehr heraus
The Project’s distinguishing technical feature is the Barrow Bridge, a seven-pier extrados bridge with an overall length of 887 m and two main spans of 230 m which are 10 m longer than the next longest concrete-only extradosed box-girder section spans in existence.
The scheme’s other principal features included:
- three at-grade roundabout junctions at Glenmore (N25), Ballymacar Bridge (N25), Corcoran’s Cross (N30), and a compact grade separated junction at Landscape (R733);
- one overbridge of the disused New Ross/Waterford railway line near Glenmore;
- 11 road bridges; and
- 13 minor structures, such as accommodation underpasses.
