Sabo Bridge reopens, again

A Minneapolis pedestrian bridge reopened late Monday for a second time, after nearly $1 million in repairs, the city announced. The 215-foot bridge is considered an important link in the city's Midtown Greenway bike and pedestrian network.

The Sabo Bridge closed in February after one of the support cables broke loose. Consultant Wiss, Janney, Elstner Associates ultimately said the failure happened because of wind-induced cable vibrations, which caused cracking in diaphragm plates.

Temporary supports allowed the bridge to open for the summer, but it closed again in September to buttress the cables.

City and county officials are working to get reimbursement from the California company that designed the bridge, MPR reports.

This may not be the last time the bridge closes. Temporary closures may happen in 2013 for painting, lighting and screen installation, the city says.
