The Tin Factory junction is a road junction in Bangalore, India. Located near Krishnarajapuram railway station on Old Madras Road, the junction witnesses high traffic congestion[1] and is one of the worst traffic bottlenecks in the city.[2] The junction connects the Outer Ring Road IT cluster of Mahadevapura–Marathahalli–Bellandur with areas along the National Highway 44 such as Hebbal.

In 2018, Bangalore Traffic Police installed a traffic signal at the junction in order to ensure free vehicular movement.[1] In 2019, Government of Karnataka announced that a flyover would be constructed at the junction which would connect the Outer Ring Road cable bridge with Benniganahalli Flyover.[3][4] In November 2019, a 17-kilometer BMTC priority bus lane was inaugurated between Tin Factory junction and Silk Board Junction.

A Namma Metro station, named Benniganahalli, at Tin Factory junction has been constructed on the Purple Line. A plan to build a double-decked Metro-cum-flyover corridor at the junction was dropped after BMRCL found the proposal to be infeasible
