Aerial Lift Bridge
Duluth’s Aerial Lift Bridge
The aerial lift bridge is one of Duluth’s most iconic and awe-inspiring sights. As far as landmarks go, only the grandeur of Lake Superior looms larger. At 138 feet tall (42 meters) and 390 feet wide (119 meters), this steel bridge spans the Duluth Shipping Canal, majestically connecting the sandbar of Park Point with the rest of Duluth. But its most remarkable feature is a suspension system that raises the bridge to a height of 135 feet (41 meters), allowing colossal ships to pass underneath. It’s the very story of Duluth’s rise as one of the Midwest’s most prominent port cities. Get a real-time view of this engineering marvel right now!
A Brief History of the Aerial Lift Bridge
The story of the aerial lift bridge is inseparable from the history of Duluth’s maritime and industrial legacy. It’s a testament to innovation, resilience, and the unwavering spirit of a city that refused to be left behind.
- 1870: The Lake Superior & Mississippi Railroad begins daily freight and passenger service, transforming Duluth into a thriving industrial hub. The demand for shipping commerce on Lake Superior sets the stage for a new port.
- 1870: The steam-powered dredging barge, Ishpeming, begins cutting the Duluth Ship Canal through the swampy gravel of Minnesota Point.
- 1871: The first canal cut is completed, connecting St. Louis Bay with Lake Superior, but separating Minnesota Point from the rest of the city. This creates a need for a permanent connection to what becomes known as Park Point.
- 1896: U.S. Congress appropriates $3 million to make the Duluth-Superior Harbor the most modern in America. The project widens the canal and leads to the construction of two concrete piers, South Pier and North Pier.
- 1899: Inspired by a revolutionary aerial transfer bridge in France, Duluth City Engineer Thomas McGilvray begins drafting plans for a bridge to span the Duluth Ship Canal.
- 1900: The Duluth Canal Bridge Commission is established, gaining the proper approvals to build the bridge and eventually awarding a contract to Modern Structural Steel.
- 1905: On February 23, 1905, two hundred people witness the ferry car’s first crossing. McGilvray himself controls the car, which glides across the canal in just over a minute. The bridge begins regular service in March.
- 1905: On April 8 – the first weekend day the bridge is open to the public – an astonishing 32,595 people board the ferry car in a 12-hour span, showcasing the immediate need and popularity of this unique solution.
- 1909: Construction begins on the North Pier Light. At 37 feet tall, its electric lamp can be seen eleven miles away, guiding vessels into the harbor.
- 1929: The original ferry car system is replaced with the innovative lift bridge we know today, providing a faster and more efficient way to accommodate the growing port traffic.
- 1973: The aerial lift bridge is deservedly added to the National Register of Historic Places, solidifying its status as an icon of American engineering and Duluth’s rich history.
