Upgrades
The route was revised in 2005/2006 to include a new section between the M50 and N11. No further planned amendments to the route have been publicised as of 2006, but the N31 would be affected in the event of an Eastern Bypass of Dublin. The current M50 would connect at the southern end of this via a link on a similar alignment to the first half of the current N31.
