Standing 400 feet tall, the new ACUITY Insurance Flagpole is the tallest flagpole in North America. Visible from a considerable distance, the flagpole is located on the company's headquarters campus along Interstate 43 between Milwaukee and Green Bay on Lake Michigan.

Erecting a flagpole of such height where temperatures frequently fall below zero has required a team of experts to ensure structural integrity and maintainability. The pole supports a 60-foot-wide by the 120-foot-long American flag. A brick paver patio featuring the names of Sheboygan County residents killed in active duty is installed at the flagpole's base.
