Grand Southern Trunk Road
From Wikipedia, the free encyclopedia
The Grand Southern Trunk Road or National Highway 45 is one of the busiest highways in India.
The highway connects Chennai (formerly Madras), the capital of the South Indian state Tamilnadu, India and Theni in Tamil Nadu. The highway runs for a length of 472 kilometres.
The highway has a 4 - lane (2 X 2 each direction) road system between Chennai and Tindivanam, a town on the highway.
During night the highway experiences a high volume of traffic to and from Chennai. On an average everyday around 10,000 lorries use this highway to reach Chennai.
The highway has a number of motels along the entire stretch which provide average food.
There are few bottlenecks on this highway:
1. The Southern Railway (India) line between Chennai and Trichy cuts through this highway in many places resulting in huge pile up of vehicles on both sides of the highway, especially in the night hours.
2. In case of any mishaps on the highway the journey gets delayed by at least 3 - 5 hours.
Few infrastructure plans are proposed on this highway
1. Rail over-bridges are being planned in the railway crossings on the highway
2. The four-lane system is currently extended between Tindivanam & Trichy for a distance of around 225 KMS
