Acuity Insurance raised the tallest flagpole in the United States on July 2, 2005. The steel pole was 338 feet (103 m) high, 6 feet (1.8 m) wide at the base, weighed 65 tons (without the flag), and was sunk into a 550-cubic yard block of concrete that was 40 feet (12 m) deep, 8 feet (2.4 m) wide and reinforced by steel rods. The flag was 120 feet (37 m) by 60 feet (18 m), or 7,200 square feet (670 m²). Each star was 3 feet (0.91 m) high and each stripe was 4½ feet wide. It weighed 300 pounds.
This flag and flagpole outdid an earlier Acuity record, a flag raised June 2, 2003, atop a 150-foot (46 m) flagpole. The new flagpole was a replacement; the old pole toppled over due to stress and high winds, falling away from nearby Interstate 43. The new flagpole was designed with extra bracing and placed much farther from the highway. A powered hoist raises the flag at 80 feet (24 m) per minute, regardless of wind conditions, and is synchronized so that the flag reaches the top of the pole just as the Star Spangled Banner ends.
On October 4, 2007 it was announced that the flag pole would yet again be rebuilt to allow access to the beacon marker on top in case of light bulb replacement. The flag was rebuilt and the top section finished on April 4, 2008. On April 7, 2008 the pole, without a flag yet flying, began swaying noticeably during relatively low wind speeds. On April 8, 2008 the ball and top section were again removed, followed by a full removal of the pole.
