Work on third phase of Ring Road project between Kangayam Road and Thindal has apparently slowed down in recent weeks coinciding with the monsoon rain.
Since the earthwork is in progress, slush formation after every spell of rain has hindered the normal pace of work, sources said.
But, the Revenue Department is reported to have cleared land acquisition process till Thindal.
But for a few litigants, compensation for the acquired land has been settled, it is learnt.
The work was initiated earlier this year after determination of traffic density along Chennimalai Road.
Connectivity to Perundurai from Karur Road would obviate the need for several hundreds of lorries and other vehicles to enter into the city.
The third phase road to a width of 30 metres is being created to a stretch of 7.2 km. The project involves construction of four minor bridges and a railway bridge.
Under the first two phases, the road was laid to a length of 7.6 km from Kokkarayanpettai in Namakkal district to Kangeyam Road at a cost of Rs. 37 crore.
The stretch has been opened up for traffic.
Sources said the proposal of the Highways Department to extend the ring road from Thindal to Chithode under Tamil Nadu Road Sector Project was being pursued in right earnest.
