New speed humps have been installed at Atene and Parikino on the Whanganui River Road.
Senior roading engineer at Whanganui District Council, Brent Holmes, said they were put in place following a request from members of the Tamaupoko community.
They had approached the council regarding specific speed complaints on the road, Holmes said.
"I visited the sites, along with our safety engineer and the Tamaupoko members," Holmes said.
"We met with nearby residents to discuss and agree on locations."
