ACTON (CBS) – With a police escort and draped in American flags, a twisted piece of steel that used to be part of one of the World Trade Center towers arrived in Acton on Thursday.

The beam will become part of a monument to those who lost their lives on September 11th, 2001, including two Acton residents who were on Flight 11.

Organizers are looking to raise $30,000 in time to complete the memorial by this September, the tenth anniversary of the attacks.
