Getting your Trinity Audio player ready...POLK COUNTY—Polk County Schools will be closed again on Friday, January 30, as last weekend’s winter weather is still affecting many roads. “I want to thank our Transportation and Maintenance Departments as well as our school staff for their hard work preparing campuses and checking road conditions,” said Polk County Schools Superintendent Todd Murphy. “Unfortunately, many of our secondary roads are still not safe for bus travel. At this time, approximately 65% of our bus routes remain impacted by ice.”Friday will be a required workday for staff. The district will continue to closely monitor the weather through the weekend and will share updates if any additional schedule changes are needed.
