Duluth, MN (NNCNOW.com) - St. Louis County officials said Friday a stretch of Arnold Road would be open in time for the holiday weekend following a culvert repair.

The 1.5 mile stretch was closed earlier this week after officials pointed to beaver activity and recent rains as the cause.

Additional work to repave the road is expected in 2014.
