Weather pending, beginning today, the Winnebago County Road Department will be closing 70th Avenue northwest of Thompson between 440th Street and 450th Street for bridge replacement. The worksite will be closed to all traffic although access will be maintained to local residents. The project is expected to be completed in 2 weeks. County crews will be removing the timber bridge and replacing it with a 14 foot by 9 foot precast concrete box culvert. Questions can be directed to the County Engineers Office at 641-585-2905.
