Dec 2-3 ARM Annual Convention: Room Block available at The Depot Renaissance Minneapolis Hotel for $139 per night through 11/7/14.
Between 2011 and 2013, the Highway 22 intersections at Adams Street and Madison Avenue in Mankato had the highest crash rating in MnDOT District 7, an area that includes 13 counties in south central Minnesota. Studies recommended roundabouts at the two intersections to improve safety and decrease traffic delays. Flashing yellow left-turn arrow signals and sidewalk improvements also were recommended.
MnDOT worked with the city of Mankato and Blue Earth County to schedule the construction and route traffic. The project ran from May through September 2014 and by the end of it, 33,392 square yards of concrete pavement and 54,100 square feet of concrete sidewalk was placed as well as 10,700 lineal feet of curb and gutter.
There was significant rain delay during the third week of June, but other than that, the weather was fine for project work. The photo above is of the Madison Avenue roundabout.
