How much ship traffic goes through Superior Entry?
It seems most ship traffic going onto the lake from Duluth-Superior goes through the canal under the Aerial Lift Bridge. How much ship traffic uses the Superior Entry, which is between Minnesota Point and Wisconsin Point? Only the ships going to and from Allouez?
The Duluth Shipping News might have some information on that. Anecdotally, it looks like a couple of ships in/out every day from Superior.
I bet the port authority would know.
