The Maple River School District will vote for a fourth time on a referendum that would fund a new school. If voters approve the referendum, the $63.3-million bond would replace aging and inefficient buildings with safer infrastructure and modern learning facilities. A construction proposal submitted by Kraus-Anerson in October says if the referendum passes, construction could begin in the late fall of 2020 with the entire project complete by the fall of 2022. Polling places are in Amboy, Mapleton and Minnesota Lake. Pools will be open Tuesday from 7 am to 8 pm.
