Ontonagon County, MI, USA
In the summer of 2010, Portland Bolt won a bid to provide the fasteners for the Baltimore River Bridge in Ontonagon County, Michigan. This 100 foot long bridge replaces the old ford that would frequently wash out during rain storms. This bridge is one of many on the North Country Trail that stretches nearly 4,600 miles passing though seven states from Crown Point, New York to Lake Sakakawea in North Dakota.
We manufactured over 2,000 hot-dip galvanized, 5/8” diameter timber bolts and a variety of other ¾” and ½” diameter lag screws as well. Due to the federal funding of this job, all bolts were required to be 100% melted and manufactured in the United States. With our inventory of domestic steel and our ability to hot forge, thread, and galvanize in house, we were able provide a competitive price and meet the delivery requirements halfway across the country.
