Preliminary construction work on the new St. Croix River bridge began last year, and has been picking up steam in recent weeks — all without the benefit of a traditional groundbreaking ceremony for one of the largest public works projects in the state. That will be corrected in Stillwater on Tuesday.

When: 2:30-3:30 p.m.

Where: Ceremony will begin at the Water Street Inn, 101 Water St. S., Stillwater, at the western end of the Stillwater Lift Bridge. Official groundbreaking will follow at nearby Lowell Park.

Who: Elected officials from both Minnesota and Wisconsin, including U.S. Sen. Amy Klobuchar, Gov. Mark Dayton and Gov. Scott Walker, are expected to attend.
