The Hennepin County Board on Tuesday signed off on a plan to make improvements at six intersections on Hiawatha Avenue that are aimed at making it easier for pedestrians and bicyclists to cross the busy highway.

Construction is scheduled to begin this summer at 28th Street, 32nd Street, 35th Street, 38th Street, 42nd Street and 46th Street. Work will continue into 2014.

Part of the Minnehaha-Hiawatha Community Works project, the upgrades include curb extensions, wider crosswalks, wider medians, ADA-compliant ramps and pavement treatments.

The cost of the project is $850,000. Hennepin County and the city of Minneapolis will kick in $250,000 each and the Minnesota Department of Transportation will contribute $350,000.
