The R840 is an extremely short, unsigned, link road in Dublin City Centre, better known throughout as Earlsfort Terrace.
The road is very difficult to drive in a private car. The northbound side is open to buses and taxis only; the southbound side can only be accessed in a car from Leeson Street, in which case you wouldn't use it as a through route.
Its existence as a numbered route appears to be to provide an alternative route to the R138, which is affected by the Leeson Street one way system, but this purpose has been made redundant by road layout changes at St Stephen's Green. As a road it also forms part of a one way system with Harcourt Street, and a route around one of the turn bans on Hatch Street Lower.
It does at least take in the National Concert Hall on its short journey.
