The National Highways has started removing encroachments at Kavundampalayam so that the Corporation can take up underground drainage works.
An official of the NH told The Hindu that the eviction started on Monday and it was likely to be completed on Tuesday.
Encroachments would be removed for 400 metres at Kavundampalayam (on Mettupalayam Road).
The NH had widened the road for 11.6 km from the Saibaba Temple junction to Narasimhanaickenpalayam almost two years ago.
There was 15-metre space beyond the widened road and the underground drainage pipes could be laid only along the edge.
The encroachments at the location were a bottleneck to the project and had to be removed. A survey was conducted on Monday to identify the exact space available, the official said.
M. Devendran, secretary of Mettupalayam Road Protection Association, said that the encroachments on the entire stretch of the road should be removed.
In some areas, the road had to be dug up for the underground drainage project.
The association was planting trees on either side of the road.
If the space on either side had to be dug up for laying cables, water pipes, etc, the trees had to be cut again.
All Government departments should jointly plan on the space needed for laying cables and pipes and earmark area for that.
The encroachments should be removed so that there was enough space, he said.
