Update: 12/5/2019 09:00 Duluth Lift Bridge in service.
Update: 12/5/2019 - 07:00 Deicing will continue on the Lift Bridge today.
Update: 12/04/2019 - 16:00 The lift bridge remains out of service until further notice.
Due to heavy ice accumulation on the Lift Bridge, it will remain closed to boat traffic as deicing efforts continue.
The 900 ton bridge span is balanced by two 450 ton concrete weights on either side. Usually the span can easily be lifted by electric motors, however, they cannot lift the additional weight of the ice.
