The image on erosion of the slopes at Jalan Simpang Pulai-Cameron Highlands which has gone viral on the social media is an old picture.

The Perak Public Works Department (PWD), in a statement which was posted on its Facebook account, said the picture was taken at FT185 Section 44 of the road in late 2014.

The department said installation of bored pile retaining structure had been carried out at the location under the supervision of the Kinta PWD and the work was completed early this year.

"The Kinta PWD will conduct an inspection at the location today," it said.

The image of the slope erosion was sent though the WhatsApp application since yesterday with a message advising the people to be cautious when travelling on the road.
