Modi visited the Chenab bridge on Friday with tight security, waving an Indian tri-colour flag before boarding a test train that passed through picturesque mountains and tunnels to reach an inauguration ceremony for another high-elevation bridge named Anji.

The bridge will connect the valley region of Indian-administered Kashmir with the rest of the country by train.

The world’s highest railway bridge, an ambitious piece of engineering across a mountain valley in Kashmir, was opened Friday by Indian Prime Minister Narenda Modi, just weeks after a deadly tourist massacre in the Himalayan region sparked a brief conflict with neighboring Pakistan.
