Several smaller roads around Castlebar, the N26 from Ballina to Foxford, the R310 from Ballina to Castlebar, the roads from Balla and Bohola to Kiltimagh and from Kiltimagh to Kilkelly and Knock... all pretty much done.
I'm tracing in the Westport and Ballina railway lines from the overhead imagery, but it's hard to get them accurate. I might have to get a train to Dublin sometime, and I'll bring the GPS.
More streets and local roads as I travel them...
