Bridge Symbol over Polygons

We have a fire run book that has a few different scales (1:3,000 the most detailed). When a road crosses over our rivers (polygons at this scale) and our one large lake at this scale we want a bridge symbol to span the width of the water body. How would we do this? The cartographic representation tool for creating an overcross and undercross appears to only work with intersecting lines. The main river running through our county (Russian River) varies in width drastically from the mouth of the river to the northern portion of our county. We are working within ArcGIS 9.2.

Any help is greatly appreciated.

Mapping Center Answer:

You can use any polygon feature class as the basis for masking.  Most people think to use masking only if they can use the Feature Outline Masks tool.

That means you can just draw some polygons using the editor that can be used to mask out the portion of the river or lake that is near the road.
