    There is a strong case for detrunking the N87. This won't reduce the accident rate though.

    The N55 is crap but some work is being done on the dangerous bits and that may get it below 0.15 after this year.
    What's being done with the N55? (I used to use this road a lot years ago).

    Anything outside Cavan?

    Also this might be slightly off topic, but what is the AADT that causes a route to justify Dual Carriageway (for example, 2+2)?
