Bengaluru: Prime Minister Narendra Modi inaugurated two stretches spanning 80 km of the Bengaluru Satellite Town Ring Road
One of them - the 37.8-km stretch linking Doddaballapur with Hoskote via Devanahalli - opened to traffic last year and toll collection started on November 17. While the second stretch - a 42-km, six-lane road connecting the industrial town of Dobbspet to Doddaballapur - has been opened, toll collection is expected to start on April 1. This stretch was to open in February, but works related to the construction of a road overbridge at Doddabelavangala delayed it. The Doddaballapur-Hoskote-Devanahalli stretch was built at a cost of Rs 1,317 crore. The Dobbspet-Doddaballapur section cost Rs 1,438 crore to build.
The 288-km Satellite Town Ring Road (STRR) is being constructed to link Bengaluru with neighbouring towns such as Dobbspet, Devanahalli, Hoskote and Ramanagara. Once fully ready, it will eliminate the need for long-distance commercial vehicles to enter Bengaluru. Traffic moving between satellite towns will also be able to bypass the city.
