DULUTH, Minn. (AP) -- The 2011 shipping season is ending on Lake Superior.
The last laker of the season pulled into port in Duluth Wednesday.
The Soo Locks near Michigan's Upper Peninsula connecting Lake Superior to the lower Great Lakes close at midnight Wednesday. The locks are closing three days later than usual because of the warm weather. Some ships will continue to ply the lower lakes.
Eight ships are laid up for the season in Duluth and Superior, Wis., this winter.
Duluth Seaway Port Authority Facilities Manager Jim Sharrow tells Minnesota Public Radio News those ships will receive millions of dollars in repairs to try to minimize any delays next season.
Sharrow says tonnage shipped through the port was down this season, despite Minnesota's taconite industry running at full capacity.
