In Chennai, the Rs 600 crore Ennore Manali Road Improvement Project (EM­RIP) would miss the Dece­mber deadline for its completion due to some hindrances. EMRIP was proposed in 1998, which envisages improvement of about 30 km road network in North Chennai to ease flow of truck traffic from Che­nnai and Ennore ports and improve road connectivity between ports to national highway network.    National Highways Authority of India (NHAI) has so far completed 75 per cent of the road project. Most of the widening and improvement works on Tiruvottiyur-Ponneri-Pa­nc­hetti Road (9 km), nor­thern segment of Inner Ring Road (8.1 km), Ennore Expressay (6 km) and Manali Oil Refinery Road (MORR) (5.4 km) were completed except for few stre­tches where the land was not handed over, NHAI official said.    Delay in shifting of the drinking water pipeline run­ning beneath the MORR has affected road widening works, NHAI explained.
