It is understood that a decision on the proposed Galway City Ring Road has been further delayed.
An Bord Pleanála is considering evidence given during the course of a lengthy oral hearing into the application last year.
A decision was expected by the end of this week, but it is thought deliberations by the planning board are likely to continue beyond then.
The N6 Ring Road plan follows a failed attempt to construct a bypass of Galway city more than a decade ago.
Three years ago, Galway County Council submitted a formal planning application for the new 18km route through the city.
The proposed ring road would cost €600 million and would run from a location close to the existing M6 to a site west of the village of Bearna.
Compulsory acquisition notices have been issued to around 500 landowners along the route.
The project would entail the demolition of 44 properties, around 40 of which are occupied at present.
Galway County Council estimates the road would take three years to construct and would involve a number of tunnels, as well as a viaduct over the River Corrib, on lands north of NUI Galway.
