There, it changes to an off-street bike lane until the junction with the R114 road, where it switches back to an on-street lane. Following the junction at Ely Arch, there is an off-street bike lane until the crossroads at Dundrum. After this, only short stretches of the route have on-street bike lanes, though there are plans to add to this route in the proposed Goatstown development plan.

Future plans

A feasibility study has explored the idea of running the proposed Luas Line E along the Upper Churchtown Road from the existing Luas Green Line at Dundrum, before turning off to the R821 road, towards Nutgrove. However, this project is unlikely to proceed soon due to scarce revenue and doubts about the sustainability of the line. Currently, there are plans to upgrade the junction with the R821. The proposed Goatstown development plan is likely to make small changes to the road layout at that section of the route. In 2021, an orbital bus route was proposed along the R112 from Walkinstown to Blackrock.
