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.

The Sabo bridge, which was closed after a pair of support cables broke in February, is reopening Friday afternoon to foot and bike traffic. Structural support was added underneath the bridge deck. Minneapolis is awaiting a report on what caused the cables to break loose.

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.

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.

Hennepin County and the city of Minneapolis released this press release Friday. In short, a preliminary report suggests that wind is to blame for the failure of two cable connections on the Martin Olav Sabo pedestrian and biking bridge in Minneapolis. The bridge was closed from Feb. 19 to June 1.

Part of University Drive was closed to traffic Saturday night after concrete had fallen from a pedestrian bridge near the St. Cloud State University campus, the St. Cloud Times reports. No injuries or damage was reported. The bridge remains closed to pedestrians until further notice.

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.

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.
