If you notice roadways closed and emergency response teams in the area of Garfield Avenue this morning in Duluth, don't panic - it's only a drill.

Duluth Police and other emergency response teams are holding a multi-agency emergency exercise that started around 7 am, and continues until 1 pm today (Wednesday, June 11). The Comfort Systems building on Garfield Avenue is at the heart of this exercise.

Both of the northbound lanes of Garfield Avenue between Helberg and Birch Streets will be closed to traffic, along with a portion of Helberg Street. Everything should be back to normal by early to mid afternoon, following the exercise.
