Incorrect.  A sharrow is used on a designated bicycle route to indicate 
what part of a shared lane bicyclists should use (ideally the center of 
the chevrons) and to remind motorists that they're driving on a bicycle 
route.  It doesn't indicate what network (LCN/RCN/ICN/NCN), just that the 
lane is one on a designated bicycle route where bicycles frequently use 
that lane.

Downtown Portland has plans on putting these markings on all lanes of 
most downtown streets soon.
