The Dahej Bhavnagar railway sea link bridge is a planned bridge in Gujarat, India.
Background In 2004, the original idea of building a railway bridge between Dahej and Ghogha in Gujarat was first proposed to Railway Ministry by mechanical engineer Vikram Zaveri. Details of the project were published in a Gujarati newspaper Janmabhoomi on 2 August 2004. In 2009, ferry service was approved by the Gujarat State Government on the same location and was inaugurated by PM Modi in 2017.
The 2004 proposal for the railway bridge was sent again to PM Modi in 2017, who forwarded it to S. C. Jain of Executive Director Works, Railway Bhavan. His response was posted on pgportal.gov.in on 23 April 2018.

Kalpasar Project The proposed Gulf of Khambhat, Kalpasar Project is an ambitious water resources initiative of the State Government of Gujarat. The project includes a proposed highway-cum-rail corridor over the dam across the Gulf of Khambhat. The corridor is expected to reduce the travel distance between Bhavnagar and Surat by approximately 179 km, from about 356 km through the existing land route to about 177 km via the proposed dyke corridor.
Location and Length of the bridge
If the proposed sea link bridge is built along a straight line connecting Dahej and Bhavnagar port, then the length of the bridge over the waters of the Gulf of Khambhat will be about 30.8 Km, and if it is built along a straight line connecting Dahej and Ghogha, then the length of the bridge over the waters will be about 26.1 Km.
