“A 48-Year-Old Bridge Revitalized Through Rust-Anode Primer Technology”

Introduction: In the realm of civil engineering, the preservation of infrastructure poses a constant challenge. In 2016, the Quebec Ministry of Transportation (MTQ) brilliantly tackled this challenge by embarking on the complete regeneration of a 48-year-old galvanized steel bridge. This ambitious project, executed on the St-Wenceslas Bridge in the central region of Quebec, proved to be a remarkable technical feat.

Introduction: In the realm of civil engineering, the preservation of infrastructure poses a constant challenge. In 2016, the Quebec Ministry of Transportation (MTQ) brilliantly tackled this challenge by embarking on the complete regeneration of a 48-year-old galvanized steel bridge. This ambitious project, executed on the St-Wenceslas Bridge in the central region of Quebec, proved to be a remarkable technical feat.

Rust-Anode Primer Technology: The MTQ opted for an innovative approach by employing Rust-Anode Primer technology to regenerate the entire bridge. Following a series of rigorous tests in their laboratories, the choice of this technology proved to be the ideal solution for restoring the bridge to its former glory.

Challenges and Adaptations: As is often the case in refurbishment projects, the St-Wenceslas Bridge presented unique challenges. Abrasive blasting with SSPC-SP16 was undertaken to preserve the hot-dip galvanized zinc in good condition. Additionally, design modifications were made to enhance the bridge deck and structure drainage systems, ensuring a complete and effective revitalization for decades to come.

MTQ Approval: This revitalization project marked a turning point, as the product used, Rust-Anode Primer, received formal approval from the MTQ. Today, it is the sole approved product for the complete re-galvanization of galvanized or metallized steel structures at the Quebec Ministry.

conclusion

The revitalization of the St-Wenceslas Bridge not only preserved a key element of infrastructure, namely the galvanic protection provided by zinc, but also paved the way for an innovative approach in the preservation of metallic structures. This project demonstrates that, even after more than 40 years, technology and engineering can collaborate to ensure the longevity of essential works of art in our society.
