Chennai: In an effort to ease traffic congestion along the arterial Grand Southern Trunk road at Pallavaram, the state highways department has proposed to construct a three-lane unidirectional flyover with a pedestrian subway at the intersections of Sandhai Road and Kundrathur Road on GST road.
The highways department has called for the tenders for the flyover project, which will be constructed at a cost of Rs 52.45 crore. It is scheduled to be completed in 18 months from the date of issue of the work order. Contractors can apply for the work until January 30.
The 1.5 km stretch of GST road in Pallavaram area has three major intersections with the major arterial road of Old Trunk road, Sandhai road and Kundrathur road. Due to the heavy traffic movement on GST road and on others intersecting it, the stretch suffers congestions during peak hours.
The traffic density on GST road and Kundrathur road junction is estimated at 15,450 passenger car units. As per Indian Road Congress norms, a flyover should be constructed at a junction if traffic density exceeds 10,000 PCU.
According to a senior highway department official, the 1.5 km long flyover will carry traffic of GST road from Tambaram to Gunidy direction, which avoids major conflict with right turning traffic movement for Sandhai road, Kundrathur road, Old Trunk road and other minor cross roads. Traffic movement on other side of GST road from Guindy to Tambaram direction will be improved with three-lane road with footpaths.
Besides a two-lane service road will be laid adjacent to the flyover along Tambaram-Guindy direction. Motorists said the construction of a flyover would ease traffic flow and reduce travel time.
