The Itasca County Highway 62 bridge is another prestressed concrete girder bridge, common in these parts. This one features tubular steel pilings to form bridge piers. These pilings are driven into the riverbed, then they are cut off with their tops being level. A concrete cap is then placed on top of the pilings. This provides a base to support the girders. The advantage is far less disruption to the river. This type of pier is most often used when bedrock is too deep to use as a base for footings. The end piers have two piles driven in at an angle to provide side to side stability, while the center pier has two sets of piles driven in at an angle to provide stability down the long axis of the bridge.

Prior to this modern bridge being built, the river crossing was served by a lift bridge. A steamship once traveled this section of the river, requiring bridges to either move out of the way or be high enough for the steamer to pass under the main channel span. The lift bridge was built in 1904, and rebuilt in 1923.
