US Highway 65/Federal Avenue in Mason City Roadwork Brings Intersection Closure

Work on a major artery of travel in Mason City will mean more adjustments for motorists.

The Iowa DOT’s Mason City construction office says the 16th Street and 17th Street intersections with U.S. Highway 65/South Federal Avenue will be closed to traffic beginning on Monday, August 11th, weather permitting. This will mark the start of the final phase of the U.S. 65 reconstruction project in Mason City for 2025.

Currently, U.S. 65/South Federal Avenue is closed between 10th Street and 16th Street with the 16th Street intersection remaining open. Next Monday, that will change as the 16th Street and 17th Street intersections will close, with access to businesses in the old Sears/Target/Southport shopping area will be from 15th Street SW. 

U.S. 65/South Federal Avenue in Mason City is currently closed to through traffic between 6th Street and 19th Street. The roadway between 6th and 10th streets has been opened to local traffic and other sections will open in the coming weeks as the reconstruction continues.
