The final stage on the $6.4M widening and upgrade of Farrer Road is scheduled to start next week.
Work on the third stage will begin on Monday 4 May and is scheduled to finish on 30 June 2020, weather permitting.
This section of the project will result in alternate routes being in place and changes to how the area is accessed from Coolamon Road.
Motorists and residents are advised that from Monday 4 May, there will be no access to Boorooma or Estella from Coolamon Road.
All access to Boorooma will need to be via Boorooma Street, on the western side of Farrer Road. Sturrock Drive will be the only access to Boorooma East.
Access to Boorooma Street from the north (Junee) must be via Old Narrandera Road, Pine Gully Road and Estella Road.
