Sabo Bridge Repair
The Sabo Bridge is a 215 foot-long cable-stayed suspension bridge that opened in November of 2007 to carry bicycles and pedestrians on the Midtown Greenway over Hiawatha Avenue and the Hiawatha Light Rail line.
On Sunday, Feb. 19, pair of suspension cable connections on the bridge fractured. The bridge was closed for further evaluation and support structures were put in place under a portion of the bridge deck. The bridge reopened to bike and pedestrian traffic on June 1, after engineers determined it could safely be reopened before permanent repairs are made.
To investigate the cause of the fractures, the City of Minneapolis and Hennepin County hired Wiss, Janney, Elstner Associates, Inc., an engineering firm with specialized expertise in determining the cause of structural issues in bridges and designing appropriate repair solutions. The firm released its report on the cause and possible design solutions in late June 2012, and it can be seen here.
The report concludes that wind-induced cable vibrations caused fatigue cracking in the diaphragm plates, which resulted in two cable connections fracturing. City and County staff are in the process of thoroughly reviewing the report and technical details.
Moving forward, City and County staff and elected officials will be working to determine the best option for repairing the bridge and the timetable for that work to be completed.
This project involves work on the Sabo Bridge, which extends over Hiawatha Avenue between 26th and 28th streets.
The Sabo Bridge is currently open to regular bike and pedestrian traffic. At this time, a date has not yet been set for the beginning of permanent repairs to the bridge.
Note: Project information may change due to scheduling, weather, or other factors outside of our control. Listings will be updated as new information becomes available.) Citizens concerned with pedestrian access during construction should contact the project manager directly.
