Motorists are advised that Mary Street at the intersection of Sheridan Avenue in Ottumwa will be temporarily closing starting Tuesday, March 27. The closure is in association with the Sheridan Avenue Reconstruction project and will allow for the installation of a new water main. During this work, Mary Street will be narrowed to one lane of traffic, with intermittent complete closures. Motorists are advised to seek alternate routes around the work zone. With favorable weather conditions, the temporary lane restrictions and closures are anticipated through the end of next week.
