Quoted from the city:
Bicycling & Pedestrian Update Subscribers,
Beginning Monday, August 13, 2012, the Midtown Greenway will experience periodic closures between Abbott Avenue South and Hiawatha Avenue South. The Kenilworth Trail between the Midtown Greenway and Cedar Lake Parkway will also experience closures.
Full closures of the trails are needed to perform joint sealing and sand sealing work that will help preserve the trail surface for at least 10 years. The closures will occur in four phases - running west to east - each lasting 2-3 days. Marked detours will be provided. The work schedule is tentative and may change due to weather conditions or construction delays. The trail will remain open on weekends.
Detours and daily updates will be posted at http://www.minneapolismn.gov/bicycles/detours

This work will not impact the Sabo Bridge or the Midtown Greenway east of Hiawatha.
Note: The Dean Parkway ramp at the Midtown Greenway will remained closed into September as part of the Metropolitan Council’s Sewer Improvements Project. More information about that project can be found here
Please stay off closed trails and follow marked detours. A full closure of the trail is needed to allow crews to work safely and ensure that the new trail surface can properly dry and cure. If bicyclists and pedestrians use the trail before it is fully dry, the surface may be damaged, requiring additional, costs, maintenance and closures.
