Trinseo and Modified Concrete Suppliers Collaborate on the Gordie Howe International Bridge Project, Setting a New Standard for High-Performance Infrastructure

WAYNE, PA. (INDIANAPOLIS, IN.)-Trinseo (NYSE: TSE), a specialty materials solutions provider, has partnered with Modified Concrete Suppliers to support the construction of the Gordie Howe International Bridge-a monumental infrastructure project set to transform the connectivity between Detroit, Michigan, and Windsor, Ontario. This bridge is not just a structure; it represents a significant leap forward in engineering excellence, designed to facilitate international trade and alleviate congestion at existing crossings. Central to this achievement is Trinseo's state-of-the-art Modifier A™/NA latex admixture, crucial for ensuring the bridge deck's longevity and performance.

Spanning an impressive 1.5 miles across the Detroit River, the Gordie Howe International Bridge is engineered to endure heavy traffic, harsh weather conditions, and the relentless wear of daily use. To meet the bridge's stringent performance standards, Trinseo's Modifier A™/NA latex was selected for its proven ability to enhance the bonding, flexibility, and longevity of the concrete. This advanced latex polymer was incorporated into the concrete overlay mix design, yielding a latex-modified concrete (LMC) solution that significantly enhances the concrete's resistance to cracking, shrinkage, and environmental degradation.

"The Gordie Howe International Bridge is a once-in-a-lifetime project, and we are honored to contribute to its success," said Chuck Fifelski, Senior Technical Service Specialist, R&D, Trinseo. "Trinseo's Modifier A™/NA latex was the perfect solution to meet the project's rigorous performance criteria, providing enhanced bonding strength and flexibility, while ensuring the durability of the bridge deck over its expected 30+ year lifespan. This project demonstrates how high-performance materials, like Modifier A™/NA latex, can play a pivotal role in setting new standards for infrastructure."

Collaborating closely with Modified Concrete Suppliers, a leading contractor specializing in bridge deck overlays, Trinseo's latex was effectively integrated into the bridge deck construction. Modified Concrete Suppliers expertly applied the latex-modified concrete overlay, ensuring that the concrete adhered to the specific performance requirements of this landmark project. The collaboration between Trinseo and Modified Concrete Suppliers underscores the power of teamwork in addressing large-scale infrastructure advancements.

"Partnering with Trinseo has been instrumental to our success in the Gordie Howe International Bridge project," said Caleb Austel, President of Modified Concrete Suppliers. "The technical expertise and high-performance materials provided by Trinseo were essential in achieving the extraordinary strength and durability demanded by this bridge. With Modifier A™/NA latex, we

are confident that the bridge will stand the test of time, minimizing maintenance needs and delivering substantial long-term cost savings."

The application of the latex-modified concrete overlay on the Gordie Howe International Bridge promises an impressive extended service life of over 30 years, drastically reducing repair needs and supporting long-term financial efficiency. This further solidifies the value of incorporating LMC in large-scale infrastructure projects.

Slated for completion in Fall 2025, the Gordie Howe International Bridge will create a vital new conduit between the United States and Canada, enhancing trade and travel while setting a new standard for future infrastructure developments.
