The OSM inspector displays overlapping roads (but not other overlapping
features):

http://tools.geofabrik.de/osmi/?view=routing&lon=-77.76585&lat=41.30639&zoom=14

There's also ways to download OSM inspector information through a WFS
interface (see OSM wiki) should you want to somehow post-process that
information.

I'd like to think that fixing these might make a good MapRoulette
challenge but then not all editors are equally suited to deal with such
problems. I usually fix these problems manually in JOSM (where the
middle mouse button lets you select between several features under the
pointer).

Not automatic fix has ever been proposed and it would probably be very
difficult to do it right.

Bye
Frederik
