The four-lane flyover will be 475 metre long and 17.2 metre wide and connect the traffic from Poonamallee to Guindy. Officials of the Highways Department said the work started in March 2010. Four piers and retaining wall for the ramp are under construction on the Poonamallee side.
The flyover was initially designed to have two columns with two-lane carriageway on either side. It was later decided to make it a single column facility with a four-lane carriageway to limit the disruption to the drinking water pipeline along the stretch.
Under the revised project plan, pipeline running to a distance of 100 metre only need to be shifted and a provision of nearly Rs.5 crore has been made towards this, the officials said.
A total of 8,000 sq.m. land is required for the project and once the sanction for the demolition process is given by the revenue authorities the flyover would be ready in 12-15 months.
