At its opening time it was the world's longest road tunnel.

At the start of the project it was the longest road tunnel being built in the country.

Construction started in 1962 and the road tunnel was opened on 27 February 1964.

No sign of the former station is visible on the surface or from the road tunnel however.

It is the fifth longest road tunnel in the world.

A road tunnel is built there at the altitude of 3130m to 3180m above the sea level.

After the intervention, all the road tunnels in the city were cleaned up.

Take a taxi through the road tunnel underneath the water to reach them.

A report in 1830 rejected the road tunnel due to concerns about building damage.

This earliest road tunnel, now government owned, opened in 1972.
