There's also an advanced way of checking highways (or other objects) 
that, like all advanced editing, requires JOSM ;)

1. download an area of interest (pbf) from Geofabrik;

2. using Osmosis, extract all major highways - or, if you want, other 
objects of particular interest to you:

osmosis --read-pbf extract.osm.pbf --tf accept-ways 
highway=motorway,motorway_link,trunk,trunk_link,primary,primary_link 
--used-node --write-xml filtered.osm

3. open filtered.osm in JOSM

4. run the license change check (requires license change plugin)

5. you now have a good picture of where objects of interest are threatened.

In contrast to Simon's list, this will also report problems with 
constituent nodes. Caution: Trying to re-map with only the filtered.osm 
file loaded is bound to cause trouble as you will be deleting nodes that 
are still used by other objects; make sure to download an area around 
where you plan to remap first.

Bye
Frederik
