Sathuvachari-VIT High Road opens in Vellore to ease Katpadi traffic

What Happened

The State Highways Department opened a new four-lane stretch known as the Sathuvachari-VIT High Road, costing ₹90 crore, to public use. The route runs off the Chennai-Bengaluru Highway (NH 48) near the Collectorate in Vellore and links Sathuvachari with Kangeyanallur, close to the Vellore Institute of Technology campus. A new bridge across the river was constructed as part of the project, featuring a footpath and a median. The entire corridor includes two minor bridges and 20 culverts. Officials indicated that the new route will enable heavy vehicles such as trucks, tipper lorries, and tankers to bypass the congested Old Katpadi Road to reach NH 48, thereby reducing congestion around the Green Circle roundabout and in the Katpadi area. The main road is 15 metres wide and incorporates a 2.5-metre median. The new bridge connected to the route is 475 metres long and 15 metres wide, and it is designed to sit at least three metres higher than the existing Katpadi flyovers built in 2009, preventing potential inundation and damage to the carriageway. Motorists were advised that safety features such as reflectors, blinkers, and pedestrian markings would be installed, and that the end of the stretch would be reinforced to avoid vehicles leaving the carriageway. The project aims to provide the shortest route for travel between Katpadi and Vellore, allowing access to NH 48 while bypassing the congested Katpadi flyovers.

Why It Matters

Officials expect the new corridor to relieve traffic in the Katpadi corridor by diverting heavy vehicle movement away from the Old Katpadi Road, thereby reducing congestion around critical junctions and improving travel times for commuters between Katpadi and Vellore. The route is projected to service a substantial daily volume, with estimates suggesting the stretch could accommodate about 17,250 vehicles per day. The elevated bridge design and height considerations reflect efforts to safeguard infrastructure from flooding and water flow in the adjacent river bed.

Background

The project is positioned to provide an alternative to the existing Old Katpadi Road, which currently experiences heavy traffic due to trucks and other heavy vehicles moving through the Katpadi area and toward NH 48. The new alignment intersects near the VIT campus and connects Sathuvachari with Kangeyanallur, potentially reshaping local traffic patterns and reducing load on the established Katpadi flyovers built in 2009.
