MANKATO - Motorists are advised of lane closures and speed reductions on Minnesota 60 at Heron Lake beginning April 29, as crews begin the construction of J-turns to improve the safety at the intersections at Heron Lake.

The westbound and eastbound Minnesota 60 lane closures are between Jackson County 24 and Jackson County 43 and will be in place until early August when the project is complete. No detour is anticipated for construction activities; at least one access to Heron Lake will remain open at all times.

The project consists of constructing three J-turns, also known as Reduced Conflict Intersections, at the following locations: Minnesota 60 and Jackson County 24; Minnesota 60 and 10th Street (Jackson County 9; and Minnesota 60 and First Street (Jackson County 43).

At the completion of the Jackson County 9 J-turn construction, MnDOT is planning a demonstration event for the public. Minnesota 60 traffic will encounter a one-day detour at Heron Lake so motorists, including agricultural equipment and semi-trucks, can practice driving through the newly constructed J-turn on a “closed course.” Details on this event will be published in the coming weeks.

MnDOT staff have been visiting with area residents about the project at various venues.  However, people who still wish to talk to MnDOT staff are welcome to attend the Minnesota 60 Windom Construction open house from 4 to 6 p.m. April 25 at the Windom City Hall, 444 Ninth St.. Minnesota 60 construction in Windom may begin as early as May 6 with lane restrictions and intersection closures.
