NHAI engineers have finally zeroed in onto a three-tier grade separator/Interchange at the junction of Mysuru-Bengaluru NH-275 and ORR NH-275K. This comes after initially proposing a cloverleaf separator which proved to be cost-prohibitive considering the land acquisition involved which had to be replaced with a more compact, as efficient and economical design in the form of a three-tier separator. It is noteworthy to mention that the cloverleaf proposal was already sent to the center for approval and subsequent land acquisition. The cloverleaf structure is estimated to cost over 450 crores as against the 200 crores in the present form, nearly halving the cost.
With the Mysuru-Bengaluru 10 lane works almost achieving 50% of the key milestones, Mysuru MP Shri Pratap Simha recently (September 2020) held a meeting with the NHAI officials to take stock of the progress and directed them to expedite the process of grade separator works.
Project Concept
The three-tier separator/Interchange comprises of an Underpass, an at-Grade suspended roundabout and a Flyover.
Underpass: 2 x 10.9 M main carriageway to be built along NH275K- Outer ring road, providing uninterrupted bidirectional flow. This will form the lowest tier.
At-grade roundabout: This shall facilitate cross over of traffic between service lanes of ORR and NH 275.
Flyover: A 6 lane flyover will cater to the NH 275 Mysuru-Bengaluru highway traffic directly entering/exiting the city.
Take a look at the concept in reality.
Tender for design consultancy and civil construction is the next step to watch for. Stay tuned for the updates.
With the completion of Expressway and the interchange, the entry and exit out of Mysuru city will be a breeze
