Prime Minister Narendra Modi on Sunday inaugurated 'Sudarshan Setu', the country's longest cable-stayed bridge of 2.32 km, on the Arabian sea connecting Beyt Dwarka island to mainland Okha in Gujarat's Devbhumi Dwarka district.

Modi began his day by offering prayers at Lord Sri Krishna temple at Beyt Dwarka.

He later inaugurated the four-lane cable-stayed bridge called the 'Sudarshan Setu', which boasts a unique design, featuring a footpath adorned with verses from Srimad Bhagavad Gita and images of Lord Krishna on both sides.

The 2.32 km bridge, including 900 metres of central double span cable-stayed portion and a 2.45 km long approach road, has been constructed at a cost of Rs 979 crore, as per an official release.

The four-lane 27.20 metre wide bridge has 2.50 metre wide footpaths on each side, it said.

The bridge, which was known as 'Signature Bridge', has been renamed as 'Sudarshan Setu' or Sudarshan Bridge.

Beyt Dwarka is an island near Okha port, which is nearly 30 km from Dwarka town, where the famous Dwarkadhish temple of Lord Krishna is situated.

At present, devotees visiting the temple at Beyt Dwarka can travel only during the day by boat, while the construction of the bridge will allow them to travel at all times, officials said.
