CHENNAI: The long wait for motorists at the Koyambedu junction for traffic to clear may soon be a thing of the past with the grade separator under construction there set to be completed by May next year.
According to officials of the National Highways Authority of India (NHAI), the implementing agency of the project, nearly 50 per cent of the work has been completed. This would be the third such facility on Inner Ring Road — after the grade separators at Kathipara and Padi junctions — to decongest traffic.
The piling work, the difficult portion of the project, is over. Construction of the superstructure is under way. Of the total 67 spans to be built, 32 have been completed, an official said.
The design of the Koyambedu grade separator would be similar to that of the clover-shaped one at Kathipara junction. However, the upcoming facility would have only three loops, except on the stretch leading to Maduravoyal, the official said. The project is being implemented at a cost of Rs.100 crore.
Traffic density at the junction, which is also used by heavy vehicles, is estimated to be one lakh passenger car units daily. Many motorists look forward to the opening of the grade separator, as it would smoothen the traffic flow at the junction connecting Inner Ring Road and Poonamallee High Road.
On the delay in implementing the project — the Koyambedu grade separator was bound to be completed two years ago — an official said the process of land acquisition had pushed the deadline to 2010.
“We still have to demolish about 20 buildings on the stretch of Poonamallee High Road towards Maduravoyal to acquire space of five to six m for the project,” the official said.
Once Chennai Metrowater completes its work of laying pipeline to transmit water from Chembarambakkam treatment plant to its network in Koyambedu, the construction would be expedited, the official added.
