The road between Moylough and Clonbern will be closed for most of August, starting from Monday, for the demolition of a bridge.
Galway County Council will be demolishing the existing bridge at Richmond, and constructing a new bridge in its place.
The R328 will be closed between Clonbern Village and its junction with the N63 at Moylough to enable these works.
The road closure will last from 9am on Monday, August 9 through to 5pm on Friday, August 27.
Local access will be maintained at all times during these works.
