Work is under way in the north west of the country to develop a major cross border project which is expected to become a reality after the UK leaves the EU.
The North West Greenway network is a joint project of Donegal County Council and Derry and Strabane Council.
Over 46km of cross border shared cycle and walking greenway routes are being planned at a cost of around €18m with most of that money coming from the EU.
Three different routes will link Donegal with Derry and Strabane.
The aim is to encourage people in the surrounding areas to walk and cycle more and also to promote tourism.
Construction is due to begin in early 2020 and be completed in 2021.
Today the team behind the project were showing proposals for the Derry to Muff route to people in Derry. Tomorrow, they will show them to people in Muff community hall.
However as one observer, Charlie McDaid from Derry, said after viewing the plans the elephant in the room today was Brexit.
He and his wife Ann think the project is a great idea and hope it will be completed quickly.
The North West Greenway Programme Manager, Jonathan Henderson said they have been told the EU funding for the project is ring-fenced but what would happen in the case of a hard border remains to be seen.
Greenways of their nature are based on freedom of movement and he hopes this project will operate as freely as possible.
