A green corridor was on Friday operationalised between Kashimira area of Thane district and Vile Parle in Mumbai to help airlift a critical patient to Hyderabad, a police official said.

The no-obstruction traffic corridor of 23 kilometres was set up after a request came in from a local hospital at 7 am, and the ambulance carrying the patient covered the distance in 35 minutes between 9:10am and 9:45am, the Mira Bhayander Vasai Virar (MBVV) police official said.
