Two major roads in St. Joseph County will be under construction starting next week.

Dogwood Road will be closed on Monday, Sep. 26, while crews install a large culvert pipe under the road.

It’s the stretch of Dogwood between New and Layton Roads that’s closing.

The road is expected to re-open at the end of the day on Monday. The detour route follows Layton and New roads to Elm Road.

Starting Tuesday, Sep. 27, on Auten Road, crews will be replacing some of the concrete on the stretch between 933 and Kenilworth Road.

Auten will be down to one lane in each direction.

The closure is expected to take place through Friday, Sep. 30. A detour route will be posted.
