Hide parts of one layer with another

Hello everyone.  Seems I only get a chance to work with ArcGIS every couple of weeks so the learning curve has been steep in some areas.

Today I'm battling with this one.  I have a shapefile of our district that just shows the borders.  I have another shapefile that has the different divisions with in the district.  The divisions shapefile also has the borders.  I've set the symbology of the divisions to have a very think line (10 points) and the board layer with a thin line (1 point).  Unfortunately the thick line shows under the thin line and I don't want it to.  Is there a way I can make it so the divisions layer shows the interior thick lines but not on the boarder?

Let me know if you need more clarification.
