The roundabout, situated at the Ashworth Drive intersection, is expected to better manage traffic in the coming months when the major road is widened to two lanes in either direction.

Prior to work commencing in October, 2014, motorists only had to contend with traffic lights as they travelled from Kelso to Bathurst.

By the end of the project, there will be two roundabouts, the second of which will become operational early next week according to a Roads and Maritime Services (RMS) spokesperson.

“A night-time traffic switch is planned for Monday, January 16 to move the Littlebourne Street roundabout to its final position, weather permitting,” they said.

Once the roundabouts are installed, the focus of the work will shift to the completion of the road median, resurfacing and landscaping.

A 40-kilometre speed limit will be in place until work is completed.

“During coming night shifts there will be speed restrictions and traffic control in place, motorists are asked to obey traffic signs and traffic controllers,” the RMS spokesperson said.

At this stage, all work is on track to be completed by the mid-2017 deadline.

Over the course of the upgrade, there has been calls to widen the highway at Raglan.

The RMS spokesperson did not rule this out as a possibility in the future.

“Roads and Maritime Services is currently investigating a corridor strategy which includes the Great Western Highway through Raglan,” they said.
