Chennai to Kanyakumari drive via East Coast Road (ECR) in January 2018

Pharma company manager, Harish got transferred to South India in end 2017.

In January 2018, he drove his Honda Amaze from Chennai to Kanyakumari via East Coast Road (ECR) in 3 days for an overview of the market.
Day 1: Chennai - Pondicherry.
Day 2: Pondicherry - Rameshwaram.
Day 3: Rameshwaram - Kanyakumari.

The route was as follows:
Chennai - Mahabalipuram - Pondicherry - Cuddalore - Chidambaram - Karaikal - Velanganni - Vedaranyam - Kodiyakkarai - Rameshwaram - Thiruchendur - Uvari - Kudankulam - Kanyakumari.

Our friend found the entire coastal route quite scenic.

Although a double lane road with no median divider almost throughout, the road surface was pretty decent. At most stretches it was difficult to exceed 80 kmph.
Some of the towns and their vicinity had high density of cycles and two-wheelers traffic spilling over to the main carriageway. It needed some amount of negotiation skills and a lot of patience. However, in general, traffic on the coastal road is sparse.
