Providing Sustainable Transport into the Future

The Ongar to Barnhill Road will provide a route for walking, cycling and travel by road. 

The route will not only link the two local areas together for better access to schools, homes, amenities and shopping. It will also link to the Royal Canal Greenway and to the Damastown Clonsilla Cycle Route, forming an important part of the Greater Dublin Area (GDA) Cycle Network.
