Know all about 119 km Bangalore-Mysore Expressway built on NH-275 in Karnataka

The 119 kilometres long, access-controlled Bangalore - Mysore Expressway has been built on National Highway (NH-275) in Karnataka state of India. This expressway will be inaugurated by Prime Minister Narendra Modi on 12th March 2023. Once become operational, it will take a little over 3 hours to cover the journey between Bangalore and Mysore in Karnataka. The ambitious 10-lane expressway on NH-275 between Bengaluru and Mysore will cut the distance in half. 

Bangalore and Mysore are one of the most significant cities in the Karnataka, valuable for both business and tourism. The currently used 4-lane NH-275 is one of the significant highways in the state. The route, however, is congested and traverses through populated localities Mandya, Maddur and Srirangapatna. 

The Bangalore - Mysore expressway is a part of the NH-275 and it will link Bangalore to Kodagu, Mangaluru, and Kerala regions. The expressway is built in two phases at an investment of around Rs 8,066 crore. Towns along the existing route will be avoided via a 51 km-long bypass road, which will be fenced on each side.

The Bangalore-Mysore expressway will reduce travel time between the major cities of Karnataka to less than 90 minutes from the current 3 hours.

The Bangalore-Mysore expressway project was proposed in 2014 and work on this project was started in two parts. The first part was started in May 2019 and on another part in December 2019.

The Bangalore-Mysore expressway includes 69 bus bays, 49 underpasses, 13 overpasses, and fencing on either side of the access-controlled, 6-lane roadway to provide a free and uninterrupted trip.

There will be a 22 km bypass for Ramanagaram and Channapatana combined, an 8 km bypass for Mandya, a 10 km bypass for Srirangapatana, and a 4 km bypass for Maddur. Additionally, Bidadi will have a 7 km bypass, and commuters travelling between the two cities can skip all these major towns.
