NHAI takes up tree plantation drive along ECR between Mamallapuram and Marakkanam
The NHAI is progressing on the four-laning project of the East Coast Road between Mamallapuram and Marakkanam, with completion expected by 2027. Additionally, a tree plantation drive has been launched to offset the environmental impact of the construction.
Why it matters
Infrastructure development is critical for regional connectivity, while environmental mitigation efforts reflect growing regulatory focus on sustainable construction.
Work to widen the stretch of East Coast Road (ECR) between Mamallapuram and Marakkanam is expected to be completed by March 2027. Around 75% of the four-laning project, for a length of 62 km at a cost of around ₹3,000 crore, has been constructed by the National Highways Authority of India (NHAI).
On completion, the road will have eight lanes in all, with two service lanes on either side that would ideally be used by local traffic. The work is being carried out in two sections.
