NEW HAVEN, Conn. (WTNH) — Communities across Connecticut will once again honor those who died in the Sept. 11, 2001, terror attacks. Of the nearly 3,000 people killed in the attacks, 161 had ties to Connecticut.

Gov. Ned Lamont directed all U.S. and Connecticut flags to be flown at half-staff on all public buildings and grounds throughout the state on Sunday to honor those killed. Flags are also lowered in remembrance of Queen Elizabeth II who passed away at the age of 96 on Thursday. President Joe Biden ordered all flags be flown at half-staff until sunset on the day of interment.

The Pearl Harbor Memorial Bridge in New Haven, also known as the Q Bridge, will illuminate in red, white, and blue lights beginning at dusk on Saturday and Sunday. Beacons that can project light nearly six miles into the night sky will be lit both nights.

News 8 compiled a list of events marking 21 years since the attacks. See the list below, organized by date. If you know of a 9/11 memorial event, share it with us.
