Oslo, Minn., April 9, 2009 -- Unusual mitigation methods to control road erosion being employed to the roadbed of Rt. 1 East of Oslo, MN while Red River floodwater overtakes the road. The 'riprap' (large stones) are diverting and breaking up water as it flows over and under the road surface; the flooding Red River of the North is higher this year than ever recorded.
