Bridge Replacement over Minnehaha Creek

Bridge Replacement over Minnehaha Creek

Project Challenge

County State Aid Highway 22 ( Lyndale Avenue South) bridge over Minnehaha Creek in Minneapolis required replacement.  The structure, located between
east- and west-bound Minnehaha Parkway, did not meet the demands of the traveling public.  Portions of the sidewalk were closed due to accelerated deterioration of steel beams supporting it, and the trail below had to be
closed due to the potential for falling debris.
