Inspectors find cracks on remaining cable plates on Minneapolis pedestrian bridge

A Minneapolis official says the failure on the Martin Sabo pedestrian bridge happened with what's known as a diaphragm plate. Deputy Public Works Director Heidi Hamilton tells the city council more of the plates are also cracked. She says it may take months to repair, but she's confident there is a retrofit solution.

Sabo bridge plates had 'poor fatigue resistance'

Cable diaphragm plates that cracked on the Martin Olav Sabo Bridge, leading officials to shut down the span for months this year, had "welded details that offer poor fatigue resistance," according to a 140-page report released Friday by the city of Minneapolis.

Sabo Bridge could reopen by June

Officials say that Minneapolis is striving to reopen the Martin Olav Sabo Bridge by June 4, the Star Tribune reports. The bicycle and pedestrian span over Hiawatha Avenue has been closed for three months, after the fracture of a steel anchor led the bridge’s tallest set of cables to fall from the mast on Feb 19.

Sabo reopens Friday until next repair phase

Workers installed a retrofitted diaphragm plate on the Sabo pedestrian bridge this week and the bridge reopened Friday morning, at least until more repairs are done to finish the project. Engineers will then plan and schedule repairs to the rest of the bridge’s diaphragm plates later this year.

Minneapolis bridge had passed inspection before cable broke

A major inspection of Minneapolis' Martin Sabo Bridge less than six months ago failed to turn up anything to forecast the broken cable that now has the bridge closed. With the support cable gone, Metro Transit has declilned to run light rail trains under the bridge -- creating headaches for commuters.
