The speed limit on a busy section of Meander Valley Road in Hadspen will drop by 20km/h this week.
Authorities say the change will make the 2.5km section safer for both drivers and pedestrians.
The current 100km/h limit will be reduced to 80km/h between the intersections of Rutherglen Road, Bartley Street and Main Street.
The Commissioner for Transport signed off on the changes after a request from the Meander Valley Council.
“The speed limit is being reduced due to pedestrian activity including school children waiting for buses, the number of intersections and the presence of curves that can affect sightlines along this section of road,” the Commissioner said.

“The new speed limit reduces the risk of crashes along the section of road by providing road users with extra time to react to vehicles turning off or onto Meander Valley Road.”
The change is expected to add just 23 seconds to a typical trip, according to the Commissioner.
The new speed limit will come into effect once the new signs go up later this week.
