N17 Knock To Collooney Project Survey Commences

A topographic and hydrographic survey will be carried out from today onwards by Murphy Geospatial Limited for the N17 Knock to Collooney [Atlantic Economic Corridor] Project.

The project will consider the upgrade of the existing N17 from Knock in County Mayo to Collooney in County Sligo.

The purpose of the survey is to establish the existing ground levels and topographic features which inform the preliminary design.


Surveys will be completed on the public road, on rivers and within privately owned lands, and are expected to be complete by the end of February 2025.

Due to the scale of the survey and the number of land/property owners involved, it is not possible to facilitate individual access arrangements with land/property owners across the study area.

The survey area can be viewed on the project website.
