Funding for the Kildare section of the Dublin to Galway Greenway won't be available until after 2016.
This is a 276 kilometre cycle route being developed under the aegis of the Dept. of Transport.
The Kildare section, 38 kilometres between Maynooth and the Meath/Westmeath border, already has planning permission.
All Department funding for greenways is fully committed up to 2016.
Minister Pascal Donohe says he "would expect that when funding becomes available that this project will be in a position to avail of that."
