KAUKAUNA, WI- (Wisconsin Radio Network) – The Fox River Navigational System Authority says the Kaukauna Locks System is open to boat traffic for the first time since the mid-1980s, more than three decades.  After years of restoration and repairs to the Veterans Memorial Bridge, boaters can now travel up and down the river, all the way to Menasha.  The locks were built more than 170 years ago in 1848.  That is also the only fully-restored locks system in the nation that is hand-operated.  Officials say there are about 25 miles of river that people will be able to navigate.  A one-mile trail system is being added alongside the locks.  It should open next spring.
