Highway 4 travellers are being advised of construction taking place roughly 14 kilometres south of Rosetown.
Crews are working to install a new culvert where the old one had previously washed away.
For months, the Highway Hotline has advised that drivers passing through this area use extreme caution.
The work is expected to last for the majority of September, only finishing by September 26 if everything goes to plan.
During the work, speeds are reduced to 60 kilometres per hour, with only one lane open for traffic. The lane that is open is also narrow, with a sharp drop-off.
Anyone driving through this work is asked to exercise extreme caution and to proceed carefully.
Updates can be monitored on the Highway Hotline, where people can find any delays, detours, or dangers on Saskatchewan roadways.
