The Petrapole-Benapole rail link was opened in 2001 after being closed for 24 years. There is a proposal to construct a by-pass road to ease congestion on the present road, connecting Benapole to NH 112 (earlier NH 35), bypassing Bangaon. On 9 November 2017, Nearly 10 years after Kolkata-Dhaka passenger train was flagged off after a gap of 43 years, a new train – Bandhan Express – was inaugurated between Kolkata and Khulna in Bangladesh (via Petrapole and Benapole), covering a distance of about 172 km. This is a weekly train and runs on Thursdays from both sides. Gallery
