The 149 kilometres (93 mi) highway has been built and maintained by the Karnataka Road Development Corporation Limited and inaugurated in 2003.

The highway passes through the towns of Ramanagara, Channapatna, Maddur, Mandya and Srirangapatna (Seringapattinam), before entering Mysore.

The road is dual carriageway and passes over the Kaveri river.
