Surat Metro Rail is a rapid transit system proposed for the city of Surat in the Indian state of Gujarat. If completed on schedule, the four-line, 100-kilometre (62 mi) metro will enter operation in 2018. In August 2012, the Surat Municipal Corporation proposed four rail routes for the metro project. The first of these would be the 19 kilometre route from Dumas Resorts to Sarthana Octroi Naka, followed by a line from Sayan to Surat, a line following Surat's outer ring road, and a route along the banks of the River Tapi from Kamrej to Ambika Niketan. The Gujarat state government approved the project later that same month.
