According to a statement released by the US Department of Homeland Security, the International Bridge is going to be closed for repairs and improvements.  When it reopens in the fall, traffic flow will be cut down severely as the bridge will function as a drawbridge.  In light of recent events, the constant influx of Canadians is no longer welcome in the United States.  We will be instituting a system whereby only 200 Canadians may enter the country each day; after those 200 have crossed, the bridge will be drawn for the day.   The same applies to Americans trying to enter Canada because although the Canadian government has not set any restrictions on travel, we at the department just dont see any reason for Americans to enter Canada.  The Department spokesperson could not be persuaded to elaborate on what the recent events might be and Canadian government officials refused to comment.

An insider has revealed that officials decided on this design after studying castles with moats.  The natural water formations of the St. Marys and Lake Superior lend themselves quite well to a moat-like structure.  And with the ever-increasing demand for national security, what is more secure than a moat?  Any person can hop a fence but it takes someone extremely determined to swim a moat, especially in typical U.P weather.

This turn of events is expected to have quite an impact on the local economy, with the University losing many students and the obvious hit Walmart is going to take by losing Canadian shoppers.  On this side, 19 and 20 year olds are going to be the ones feeling this change the most, with their loss of drinking privileges.  It has yet to be determined if this drawbridge system will be instituted across the U.S.
