State Highway 17 (Karnataka)

State Highway 17 (SH-17) is a state highway connecting the cities of Bangalore and Mysore in the south Indian state of Karnataka. The highway has a total length of 149 km. It was 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. The 15 km stretch from Bangalore Central to Kengeri NICE Road Junction is known as Mysore Road.

The 62 km Bangalore-Maddur section was upgraded under build-operate-transfer (Annuity) basis by a consortium of NCC Infra and Maytas Infra. The 49 km Maddur-Mysore stretch was upgraded by Soma under an EPC contract.

Bengaluru-Mysore highway was taken over by the NHAI in 2014 and included as a part of the Bengaluru-Bantwal NH-275. The stretch was upgraded to a 6-lane partially access-controlled highway along with 2-lane service roads on either sides in March 2023.
