MARINETTE — The Marinette City Council has approved contracting with Ayres Associates to undergo a study of the condition of beams supporting the fishing platform that is part of the Hattie Street Bridge.

The unanimous decision by the city council Tuesday was reached after hearing from Brian Miller, director of public works, at a special meeting of the Board of Public Works held prior to the council meeting.

Miller told the BPW and alderpersons in the audience that five of the 21 double tee beams that support the fishing platform had been replaced at the same time as the 2017 bridge deck project. At that time, only those five showed excessive deteriorating, most likely caused by the spray of road salt used each winter on the bridge itself, Miller said.

Wisconsin Department of Transportation recently inspected the Hattie Street Bridge storm drain pipes after they detached from the storm inlet castings, when they noticed deterioration on five additional double tee beams of the remaining 16.

In his report to the BPW, Miller wrote, “A physical inspection of the 16 double tee beams is now required to determine how much deterioration has occurred and to determine the next course of action.”

Miller said the City of Marinette would only be responsible for half of the cost of the engineering study, as the City of Menominee is co-owner of the bridge.

“I have talked with (Menominee City Manager) Tony Graff, and he has agreed (in concept) to pay for half, but has to go to the city council for approval,” Miller said Tuesday.

Miller said the Hattie Street Bridge was constructed in 1976. The fishing deck/pedestrian walkway was considered to be a unique design and was featured in several publications at the time of its construction, Miller added.

Ayres Associates of De Pere, Wisconsin, is an architectural and engineering services firm specializing in transportation, general civil, geospatial, environmental and architecture. The study of the fishing platform will cost $10,500.

Miller informed council members that the work being done to reattach the drain pipes and install additional bracing is under warranty and should be finished before winter.
