Kalyan Airstrip is an abandoned World War II airstrip at Nevali 6 km south of Kalyan railway station and 55 km north of Mumbai airport, India. The airfield served RAF Kalyan and was abandoned after the war. It is owned by the Ministry of Defence but has been encroached upon.In 2006, the site was proposed as a candidate for the second airport for the Mumbai Metropolitan Region. However, this proposal was abandoned in February 2014 as the Maharashtra government dropped the idea of examining alternative sites, having secured all necessary approvals for the Navi Mumbai International Airport at Panvel.
