ST. IGNACE, Mich. — A giant U.S. flag was again visible on the Mighty Mac as Americans observed the 18th anniversary of the Sept. 11, 2001, terrorist attacks.
The flag is displayed on six holidays each year -- Memorial Day, Flag Day, Independence Day, Labor Day, Patriots Day and Veterans Day, the website reported.
The flag also is unfurled through a new 36-foot reel system, which stores the Stars and Stripes like a roll-up window curtain on the bridge's towers, MLive reported.
The flag is lowered through a remote control device, the website reported.
