I have one polyline file (that cannot be split apart) and it has many many overlapping lines. Does anyone know a way in ArcGIS to determine which lines overlap and either: a) change the line thickness or B) offset the lines, so that one line does not hide another?

Just a partly answet to second part you of your question.

Depends of numbers of record you (if there is many it won't work much) can try to fomat data by them thickness - each line should be taken as single value in formatting this way you can try visualize them.

Hope that helps.

Sounds like a cry for topology... You can give a shot at using (Personal | File) Geodatabase topology or the topolgy tools of the Edit toolbar to find the crossing ones.

I know this forum is old and that problem is probably resolved, but since you are using arcgis, you have access to the intersect tool.

Use the intersect tool with the line layer as the only input and your output will be the segments of line that were overlapped.

in case anyone wanted to know...
