A ceremony involving a number of organizations and public officials will be held from 4:30 to 6:15 p.m. at Gold Medal Park, 10th Ave. S. and 2nd St. S. in Minneapolis. The park is close to the site of the collapse and the new bridge currently under construction.

Performers at the outdoor ceremony will include several musicians, choirs and dance companies and gospel singer Tom Tipton, who has performed at many union events.

At about 5:30 p.m., a procession that will include construction workers and first responders, will walk from Gold Medal Park to the Stone Arch Bridge, which crosses the Mississippi River parallel to the I-35W bridge. Participants will observe a moment of silence, followed by the tolling of church bells and a reading of the names of those who died. A flag will also be raised on a construction crane.

Participants in the ceremony and march will remember the 13 people who were killed and more than 150 injured during the collapse at 6:05 p.m. Aug. 1, 2007. Operating Engineer Greg Jolstad, who was working on the bridge at the time, was among those who died. The cause of the collapse is still under investigation.

The ceremony is open to the public. Metro Transit announced it will be offering free rides from 2 to 7:30 p.m. Friday for those who wish to attend. For more information, go to www.metrotransit.org
