ST. PAUL, Minn. (AP) -- Go ahead and go a bit faster on 730 miles of Minnesota highways.
The Minnesota Department of Transportation says it's raising the posted speed limit from 55 miles per hour to 60 along three highways in greater Minnesota. New signs reflecting the higher limits began going up on Monday.
State officials say traffic engineers determined that higher limits don't pose safety risks on the affected routes.
The higher limits include the entire length of Highway 75 from the state's southern corner to the Canadian border. The 60 mph limit also affects the majority of Highway 59, which also spans the state from south to north. Fourteen miles of Highway 7 will also see a change.
Eight years ago, the state raised the limit on 930 highway miles.
