Photos, video - King of the road: Big boiler makes its way to Duluth harbor
A semi pulling a 442-ton industrial boiler made its way from Twig to the Duluth harbor on Thursday, the final leg of a slow journey that started in Nebraska.
Workers used tall poles to lift power lines out of the way along the route as the convoy started in Twig at midday, traveled down U.S. Highway 53 to Haines Road, then Piedmont Avenue, then 24th Avenue West -- eventually reaching Superior Street and wending its way to the waterfront via Garfield Avenue.
The boiler was headed to the Clure Public Marine Terminal, where it was to be loaded onto the ship Erik and transported to Sarnia, Ontario.
The entire unit, consisting of two tractors, two flatbed trailers and the boiler, extended 350 feet and weighed 885,000 pounds.
