River Dee Bridge set for £130m Infrastructure Overhaul
The Welsh Government is gearing up for a significant infrastructure upgrade with a GBP 130 million (US$161.6 million) project aimed at replacing the ageing A494 River Dee Bridge.
This critical route, linking Dolgellau in Snowdonia National Park to the outskirts of Chester, is a lifeline for commuters, freight transport, and local businesses. Currently, nearly 70,000 vehicles cross the bridge daily, making it one of the region’s busiest crossings.
To ensure long-term resilience and improved connectivity, Welsh ministers have issued a Prior Information Notice (PIN), signalling the official start of the procurement process in May 2025. Contractors interested in bidding for the project have until midday on February 21, 2025, to submit their applications.
The Bridge Replacement Plan
With traffic congestion and structural wear becoming growing concerns, the most viable solution involves constructing a brand-new bridge southeast of the existing structure. The new crossing will not only accommodate traffic in both directions but will also incorporate a dedicated cycle and pedestrian pathway, promoting sustainable transport options.
Beyond replacing the bridge, the project is expected to include several critical enhancements:
- Upgrades to the A494, particularly where it passes beneath the North Wales Coast Railway line.
- A newly designed highway exit, aimed at improving traffic flow and accessibility.
- Improved safety features, ensuring compliance with modern infrastructure standards.
The replacement initiative aligns with the Welsh Government’s vision for sustainable transport and future-proofed infrastructure, which is increasingly factoring into large-scale construction projects.
Why the Upgrade is Essential
As a key artery connecting North Wales and England, the A494 is vital for economic activity, tourism, and logistics. However, the current bridge, which has served for decades, is facing issues such as:
- Structural deterioration, requiring more frequent maintenance.
- Traffic bottlenecks, leading to delays and increased emissions.
- Limited capacity for alternative transport modes, restricting pedestrian and cyclist access.
The new bridge will not only extend the lifespan of this crucial corridor but also reduce long-term maintenance costs and enhance transport resilience against climate-related challenges.
Procurement and Next Steps
The formal procurement phase will kick off in May 2025, with the Welsh Government keen to engage with experienced contractors who can deliver a cost-effective and environmentally sustainable solution. Contractors with the required qualifications and expertise are encouraged to express their interest before February 21, 2025.
A Strategic Move for Wales’ Transport Network
This bridge replacement project is just one component of Wales’ broader infrastructure strategy, which includes major road, rail, and active travel investments. By integrating modern construction technologies and sustainable design principles, the government aims to future-proof its transport network for decades to come.
With the A494 River Dee Bridge replacement poised to become one of Wales’ most transformative road projects, commuters, businesses, and local communities can look forward to a more reliable and efficient connection between North Wales and England.
