Picnickers from Spokane used to take a train to Coeur d’Alene, then catch a paddlewheel steamboat to Heyburn State Park in the early part of the 20th Century. This shot on the left shows the swinging railroad bridge in action, letting a steamboat through into the park.
This is the same swinging bridge today, though it doesn’t swing anymore. Engineers raised it high enough to let sailboats beneath it when Trail of the Coeur d’Alenes was built in about 2004. The 72-mile trail goes from Plummer to Mullan on the old railroad bed. It’s paved all the way, including this section that goes across the lake and the old swinging bridge in Heyburn State Park.
