This manhole cover is in the sidewalk (if you can call that asphalt mess a sidewalk) that accompanies North Aurelius Road as it climbs over the railroad tracks. It’s on the west side of the street, roughly between Walsh and Perkins.
All over Michigan, when you see a manhole cover or a sewer grate, the odds are good that it will display the name of the East Jordan Iron Works. They were founded in 1883 as the Round and Malpass Foundry and made cast iron parts for the lumber industry, ships, machinery, agricultural equipment, and railroads. East Jordan is in the northwest of Michigan, so the connection with the lumber industry is unsurprising. In 1885 their name changed to the East Jordan Iron Works. Since 2012, they call themselves just plain “EJ,” which I find a little disappointing. Their corporate headquarters are still in East Jordan, but they are now a multinational company, having acquired a lot of other foundries over the years. In 2017 they built a new foundry after almost 135 years in their original location, which is amazing. Happily for the town, I’m sure, they built the new one just 14 miles away from the original.
EJ has a detailed company history and timeline on its Web site. I wish all companies did this.
