Works of note on the N80 include:
a bypass of Tullamore (N52) and Moate (M6) involved the designation of some 26 km of N80 to R road resulting in a reduction in its total length.
Mountmellick inner relief road - project appears to have been abandoned.
Realigned section where it crosses over the M7 (Completed late 1990s).
Kildavin bypass (completed in the 1990s it involved passing over the village and bridging over the R724)
Southern terminus of the N80 at the N11 converted from a simple T-junction to a roundabout (2008).
