Eagle Observation Tower

Scope

Michels constructed the foundations for the new Eagle Observation Tower in Door County's Peninsula State Park. The new ADA compliant observation tower includes a 766-foot ramp that starts at ground level and rises to 55 feet at the main tower. The ramp is designed to meet Americans with Disabilities Act standards with a 5-percent grade, rising through the tree canopy to the main tower. The ramp is the first of its kind in the United States; other accessible ramps are reached by elevators.

Michels installed 116 six-inch diameter cement grouted rock anchors drilled 15 to 20 feet deep, footings and columns to support the ramp. The original tower was built in 1932, but was taken down in 2016 when its structure had deteriorated. The new tower is anticipated to last for more than 100 years.
