Authorites shut down lanes along a busy north metro highway Monday morning as four separate grass fires broke out.

Fires broke out on both sides of Hwy. 610 between Zane Avenue and West Broadway shortly after 11 a.m., said Brooklyn Park Deputy Fire Chief Todd Seitz.

All four were smaller than an acre and caused no damage to any structures. One of the fires did reach the edge of the parking lot of Target Brooklyn Park headquarters, Seitz.

At one time officials shut down the entrance and exit ramps to and from Zane Avenue, and one westbound lane of Hwy. 610. By noon, the fires were extinguished.

"Until we get a bit more rain, we are going to see more of these than we care to," Seitz said.

It was not immediately known how the fires started.

The fire serves as a reminder that conditions are ripe for grass fires. Hennepin County is among those where there is a high risk for fires, according to the Minnesota Department of Natural Resources.
