MASON CITY – The Frontage Road between the North Iowa Fairground Entrance and South Roosevelt Avenue will be close to through traffic for approximately three weeks beginning Monday, July 24th.
This closure is necessary for an Alliant Energy contractor to locate and make upgrades to the underground gas regulating system at the Northern Natural Gas Gate Station near the intersection of 4th Street SW (Highway 122) and South Roosevelt Avenue. The South Roosevelt Avenue southbound right-turn lane will also be closed for the duration of this project.
