Niayesh tunnel, opens to the public. Tehran's municipality inaugurates the longest and most expensive tunnel construction project in the capital. After almost two years and a price tag of around one billion dollars the Niayesh tunnel has opened.
Tehran being a rapidly growing metropolis of more than 13.5 million people, traffic congestion is often an issue throughout the day, and the Niayesh tunnel aims to reduce the flow of traffic. With a length of over 10 kilometers it connects the east to the west and has an internal route connecting the east to the south.
The tunnel has been built using the latest and advanced cement equipment which includes a new technology known as self compact concrete (SCC) that has internal interlocking steel beams. In addition the Niyaesh Tunnel has been built using 2012 Permanent International Association of Road Congresses (PIARC) standards, considered to be the most advanced method by the World Road Association.
