Gunnedah's new roundabout is taking shape on the Oxley Highway.
Work is progressing on the roundabout at the intersection of the highway and Boundary Road, and Roads and Maritime Services (RMS) said the concrete pours would be carried out this week.
An RMS spokesperson said the pours would be done in the early hours of the day because of high heat.
The intersection is a main thoroughfare for trucks turning onto the heavy vehicle route to travel in the direction of Coonabarabran and was identified in the Oxley Highway corridor strategy as needing an upgrade.
Access to properties in the area will be maintained at all times but traffic may be reduced to one lane on the highway and Boundary Road during work hours. A reduced speed limit will also be in place and may affect travel times.
Work on the project is expected to continue until March, weather-permitting.
