In a bid ensuring smooth flow of vehicular traffic on 61 km long stretch between Sriperumbudur and Walajahpet on the Chennai-Bengaluru bypass road is all set to start shortly. According to official sources in the NHAI, of the 326 km distance of the Chennai-Bengaluru bypass road (National Highway 4), the 61 km stretch has four lanes, while the road from Koymabedu to Sriperumbudur and from Walajah to Bengaluru six lanes. The work that began in the recent past at a cost of Rs.1,200 crore, is intended to widen the road into six lanes from the existing four lanes. The widening of projects involved building about 20 underpasses covering Chembarambakkam, Perumbulipakkam, Kaveripakkam, Vedal, Eanathur and Vallakottai. In addition, flyovers are proposed at Vanagaram, Kumananchavadi, Sunguvarchathram, Ponnerikarai, and Mambakkam, besides providing pedestrian underpasses at 22 locations.
