ROSEVILLE, Minn. (AP) -

For some Minnesota motorists, helicopters could get in the way of the commute this week.

The Minnesota Department of Transportation is warning of possible delays along Highway 169 near Belle Plaine because of a power transmission line project. Helicopters will help be stringing heavy-duty transmission lines through Friday.

The lines are part of the CapX2020 project that involves 250 miles of transmission between Brookings County in South Dakota and Dakota County in Minnesota. The first part of the line is expected to be energized later in the year.

MnDOT says state troopers will be on scene and may opt to temporarily stop traffic.
