ST. IGNACE, MI — The Mackinac Bridge tower painting project, now entering its fourth and final year, has won a second national award.

Representatives of Seaway Painting of Livonia, the contractor performing the work on the bridge, accepted the E. Crone Knoy Award this week from the Society for Protective Coatings, an industry group focused on protecting and preserving concrete, steel and other industrial and marine structures.

The E. Crone Knoy Award "recognizes an outstanding achievement in industrial or commercial coatings work that demonstrates innovation, excellence in craftsmanship or the use of state-of-the-art techniques or products to creatively solve problems or provide long-term service."

"Anyone who is familiar with the scale and size of the Mackinac Bridge can understand the planning and effort required to clean and repaint the towers," said Mackinac Bridge Authority Executive Secretary Kim Nowack. "The awards our contractors have won are a testament to the excellent work that is being done to preserve the bridge."

Last summer at the Structural Engineers Association of Illinois 2019 Excellence in Structural Engineering Annual Awards, Ruby+Associates took home the Best Neighboring State Project Award for the bridge painting platforms used in the painting project. The movable scaffold system was designed by Ruby+Associates of Bingham Farms, fabricated by Moran Iron Works of Onaway, and used by Seaway Painting.

The south tower contract is for just less than $6.5 million, with Seaway required to complete the project by December 31. Installation and removal of the platforms has required brief closures during the overnight and early morning hours on several occasions.

The original paint is lead-based, and Seaway is required to contain 100 percent of the paint as it is removed and ship it to an appropriate landfill facility. The new paint, which is zinc-based, is expected to last at least 35 years, with periodic maintenance.
