Punch’s Newbridge South bridge: design and sustainability notes for engineers
Reviewed by Tom Sullivan
First reported on The Construction Index
30 Second Briefing
Punch, COWI’s consultancy arm, has been appointed by Evara Developments to deliver detailed design and tender documents for the Newbridge South Outer Orbital Road in County Kildare, backed by €20m of Housing Infrastructure Investment Funding. The scheme comprises 790 metres of new single carriageway distributor road and a 170‑metre, five‑span bridge over the River Liffey linking Great Connell and Kilbelin, plus junction upgrades, drainage and utilities. Designs must integrate walking and cycling routes with a 9.2‑hectare River Park featuring recreational space, biodiversity measures and sustainable water management.
Technical Brief
- Punch’s commission is limited to progressing detailed design and tender documentation, not construction delivery.
- Scope explicitly integrates road geometry, bridge, drainage, active travel and environmental infrastructure into a single coordinated design package.
- Housing Infrastructure Investment Funding of €20m is already secured by Kildare County Council, de‑risking early capex.
- Evara Developments is advancing the scheme via a partnership model with Kildare County Council, affecting approvals pathways.
- The new link is framed as “critical infrastructure” for phased residential build‑out, tying transport design to housing staging.
- River Park works bundle recreational amenities with biodiversity and sustainable water management, influencing earthworks and drainage layouts.
- Managing director Tim Murnane flags scheme complexity around combining a major Liffey crossing with multi‑modal corridors.
Our Take
COWI’s recent acquisition of Punch Consulting Engineers, noted in our June 2026 coverage, means the Newbridge South Outer Orbital Road and 170m River Liffey bridge will effectively be an in‑house collaboration, which can streamline design decisions and standardisation across Irish transport schemes.
Compared with COWI’s work on the longer-span Hampton Bridge over the River Avon and the Juneau Creek Bridge in Alaska, the NSOOR’s 170m, five‑span structure sits at the smaller end of its current bridge portfolio, suggesting scope to reuse proven details rather than push novel structural solutions.
The 9.2ha River Park and sustainable water management features align with COWI’s broader sustainability advisory role for the Irish government on district heating, signalling that Kildare County Council and Evara Developments are likely to emphasise climate‑resilient drainage and biodiversity metrics in project approvals and funding cases.
