A co-worker just returned from a cross-country motorcycle trip. As they were cruising on I-90 through Minnesota they noticed that large sections of pavement were purple! We have several theories here in the office, but I'm wondering if anyone (a native Minnesotian perhaps?) knows the origin/explanation of the purple hued pavement. I've done goole, ask, and dogpile searches for this, but all I get back are links to a rose variety --named of all things--purple pavement! If you could post a link that shows a photo that would be a bonus! TIA!

It is because of the crushed rock used in the paving. I am assuming it is in the SW corner of the state that you saw that. Some of the rock comes from the Pipestone area. There is the Pipestone quarry near Pipestone, MN and also Sioux Quartzite Quarry near Jasper, MN.
If you are in the area again it would be worth stopping at the National monument!
Here are a couple of links that might help. If you contact the MN/DOT they would be able to give you specifics on what was used in the area of the road you noticed.

Hope that helps!

Maybe because of the Minnesota Vikings?

They have kind of pinkish type roads in parts of South Dakota because of the rocks they crush to make the asphalt with. Don't know.
