Notes:

• Reconstructed, 1968, but appears to have retained its original appearance. Improvements made, 2009.
• Tom Haapoja provided information about this bridge. His father worked on its construction: "Built in 1938-39. They had a sawmill on site from which they took 'select' lumber for the bridge and boat docking area. I think the sawmill was located on the present-day parking lot. Each anchor for the suspension cables consisted of 44 tons of concrete. The concrete was transported to the forms via wheelbarrows. The construction of the East anchor was difficult because the wheelbarrows travelled uphill, and each were pushed by one man and pulled by another."
  
  "It was a WPA and CCC effort. The CCC Camp discipline and logistics were provided by the US Army, but the construction supervision was provided by the WPA. About 200 Men from the Norrie CCC camp (Ironwood, Michigan) participated in the construction of the bridge and surrounding park. They worked during the cold of winter and rode to and from Camp Norrie in open trucks. Each trip took 1 1/2 hours. The architect of the bridge was 'Oakey' Johnson. The WPA construction foreman was 'Charlie' Johnson."

  "Since Oct. 2017, they have been designing, funding, and building a suspension bridge hanging off of a 70 foot central tower. The bridge, an idea sparked by a frequent hiker, runs over a valley, giving visitors an up-close view of the trees without the climb."

  "Oates says there was a perfect site [for the bridge] at Hidden Lake Gardens. There’s this sort of bowl-shaped valley. It’s called a kettle hole, a deep depression caused by a chunk of glacier falling off. The 700 foot bridge spans that ‘kettle hole’ valley."

Notes:

• This is the third Michigan suspension footbridge I've found nicknamed "Little Mac".
• Stephen Quintana writes: "One of my first projects was to be the inspector on the construction of this bridge. This was somewhere between 1994 and 1996. I remember the contractor's only experience with any Forest Service projects was installing some toilets for us. He had never done anything like this before. I wasn't on the job site the day he pulled the cables across the river, so I asked him how he did it. He said he used a fishing pole with a small weight and cast it across the river. Then he used that to pull a larger rope, then a much larger rope, then finally the cables. I thought they did a pretty good job on this bridge. I remember the cost was somewhere around $100,000 for this project."
