The Chennai Port Maduravoyal Expressway, BOT model is a 19 km long, country largest elevated expressway under construction at a cost of Rs.16,550 million, Rs.3,100 million set aside for land acquisition, rehabilitation and resettlement. It runs along the banks of the Cooum upto Koyambedu and along the median of NH4 thereon till it reaches Maduravoyal. This would ease the congestion and promote trade through Chennai port by cutting down the distance by 30 km and facilitating freight carriers from Sriperumbudur Oragadam industrial belt to the Chennai port and reducing traffic along Vandalur via ORR or Minjur by connecting two ends of the city.
The main area that is expected to benefit the most is Poonamallee, one of the most affordable hubs in Chennai with over 100 projects in the area consisting mostly ready to move in homes. The property prices here vary from Rs.4000 to 6000 per sqft and with proximity to the upcoming expressway, the attractiveness of the area is bound to increase.
