A two-year project to reconstruct Iowa 122 from South Monroe Avenue to South Carolina Avenue in Mason City will require lane closures on either end of the project beginning on Monday morning, April 2, weather permitting, according to the Iowa Department of Transportation’s Mason City construction office.

The westbound Iowa 122 lanes will be closed for reconstruction beginning Monday morning, April 16. At that time, all traffic will be moved to the eastbound lanes in a two-lane, two-way pattern with a center turn lane. The eastbound lanes will be reconstructed in 2019.
