Tatangara Bridge

Kosciuszko National Park, New South Wales, Australia

The Tatangara River bridge replaced an aging timber structure in under 12 hours, with minimal environmental impact and greatly improved load capacity.

Tatangara Bridge

This 1950s timber bridge had deteriorated, carrying a low 10‑tonne limit, and requiring expensive annual repairs that restricted access for locals and Snowy Hydro operations.

National Parks selected the InQuik semi‑modular system for its rapid installation, reduced truck movements, environmental sensitivity, and ability to meet SM1600 load rating standards.The new bridge now supports 160‑tonne loads, offers a century‑long design life, and ensures reliable access to key destinations like Tantangara Dam and Currango Homestead.

Key project points

Resilient
The 160‑tonne load rating and SM1600‑compliant design ensure the bridge withstands heavy vehicles and long‑term operational demands.

Efficient
Installation took under 12 hours with only two truck deliveries, reducing time, cost, and environmental disturbance.

Durable
A 100‑year design life and minimal maintenance requirements make it ideal for remote alpine environments.

Environmentally Sensitive
Top‑down construction and setback abutments protected the pristine waterway and reduced ecological impact.

Cost-Effective
Comparable pricing to precast options but with far fewer truck movements and lower lifetime maintenance costs.

The location

Kosciuszko National Park is a high‑alpine ecotourism destination attracting year‑round visitors for snow sports, hiking, mountain biking, and heritage tourism.

‍

The Murrumbidgee River crossing provides access to the northern side of Tantangara Dam and historic sites like Currango Homestead.

‍

Its remote setting and pristine waterways required a construction approach that protected the environment while supporting increasing tourist and operational traffic.

Challenges

The original 1950s timber bridge had a 10‑tonne load limit, deteriorating structure, and rising maintenance costs, including $15,000 in repairs the previous year.

‍

Its low capacity prevented road‑grading equipment from accessing the reservoir road, limiting park operations.

‍

Any replacement also needed to minimize truck movements, avoid waterway disturbance, and be completed before the end of the 2017 financial year.

‍

How we helped

InQuik delivered a semi‑modular bridge that arrived on just two trucks and was installed on‑site in under 12 hours, dramatically reducing environmental impact.

‍

The design placed abutments and footings away from the watercourse, protecting the river and surrounding alpine ecosystem.

‍

With a 160‑tonne load rating, 100‑year design life, and minimal maintenance needs, the new bridge now supports growing visitor numbers and long‑term National Parks operations
