Monaghan Road according to Road Traffic (Special Speed Limits)(County Monaghan) Bye-Laws, 2014.
Monaghan Street would appear to only be west of O'Duffy Street, after which it becomes Monaghan Road.

This note is correct, I buy fuel here and the receipts do say Applegreen, Monaghan Road. However, I believe that from the traffic lights up to the Diamond is called Monaghan Street
