(Portland, OR)  --  The bridges will be lifting more than usual in downtown Portland as ships sail in for the Rose Festival's Fleet Week.  In celebration of military service members and veterans, several U.S. and Canadian ships will be arriving this afternoon, as well as tomorrow.  Officials say to expect delays on public transportation during afternoon commutes.  Portlanders will have the opportunity to tour the Navy and Coast Guard ships.  If you tour the vessels, you'll go through airport-like screening and will need a photo ID.
