The STRR will comprise a network of national and national road corridors. The project is envisaged to reduce traffic congestion in the city of Bangalore by providing a bypass for freight traffic, so that heavy vehicles can travel along the outskirts of Bangalore without entering it.

Although initially proposed in 2005, the STRR green highway project gained momentum after the Modi government announced that financing and execution would be undertaken under the Bharatmala Pariyojna project. The project is expected to cost Rs 15,000 crores. While the National Highways Authority of India (NHAI) is funding 60% of the project cost, the state governments of Karnataka will fund the remaining corpus (mainly for land acquisition)

STRR is built in 3 parallel phases and involves the construction of the NH-948A and the realignment of the existing NH-648 (former NH-207).

To manage the development of STRR, the government of Karnataka set up a planning authority called Satellite Town Ring Road Planning Authority in 2016. The jurisdiction of STRRPA includes a planning area of ​​1019 km2. It will include 331 villages and 12 towns which will be connected.

80 km Dobaspet – Doddaballapur – The Hoskote section of the project is already under construction. NHAI awarded the 80 km section in two lots. Shankaranarayana Constructions (SNC) and Dilip Buildcon (DBL) run one package each

SNC is currently developing the 42 km Dobaspet – Doddaballapur section at a cost of Rs 1,350 crore which includes a 2.5 km long flyover at Doddaballapur.

Dilip Buildcon is a 38 km four-lane section between the Dodaballapur bypass and the Hoskote section. The company won the project for Rs 1,278 crore in Hybrid Annuity Mode (HAM).

In another boost to the project (STRR), the Ministry of Environment, Forestry and Climate Change (MoEF&CC) has given environmental clearance for the 79 km stretch of the project between Ramanagar – Magadi-Dobaspet.

Bangalore has attempted several major ring road projects to improve its city-region connectivity and alleviate traffic congestion.

A ring road (PRR) is also planned over a section of 73.50 km with a 100 meter wide road. When completed, it will connect Tumakuru in and Hosur roads, via Hessaraghatta Road, Doddaballapur Road, Ballari Road, Hennur Road, Old Madras Road, Hoskote Road and Sarjapur Road. With NICE Road, which connects Tumakuru Road and Hosur Road via the North West, West and South West areas of the city, Bangalore will have a 116 km long bypass on its outskirts.
