A building maintenance worker on a telescoping boom lift was pinned to the exterior of the Winthrop Building at 325 W. First St. in Downtown Duluth today. The brick sidewalk in front of the building collapsed under two of the boom lift’s four tires, causing the boom to shift, pinning the worker to the building under the weight of the boom. The lift tipped into a vault that extends under the sidewalk.

Duluth Fire Department crews extricated the worker using air lift bags. The worker was transported to a local hospital for treatment of non-life threatening injuries.
