Work to install speed bumps along Koutu Rd between Taharangi and Karenga Sts will start this month.
Planned work to renew the foundation of the road has meant the Rotorua Lakes Council was able to take the opportunity to install speed bumps in areas where residents have said it is unsafe, the council said on its website.
Koutu Rd was one of about 100 roads in the district that residents wanted improved and the council said it had been prioritising these based on recorded speeds, risk and crash rates.
Traffic surveys taken on Koutu Rd had shown average traffic speeds were faster than the speed limit.
The work to improve the road includes removing the current seal and renewing the foundation of the road underneath.
