Red Line Tunnels

The Red Line consists of 12 kms of at-grade alignment and 12 kms of underground. There are 10 stations along the underground portion of the alignment, at a distance of approximately 1 km from one to the next.

The excavation is being done by 8 Tunnel Boring Machines (TBM). The tunnel excavation phase will commence in 2017. Each TBM is 115 meters long, 7.5 meters in diameter and weighs approximately 900 tons.

Each TBM is in essence a giant underground factory capable of carrying out three functions at once: underground excavation, removal of the excess soil and construction of the tunnel lining using concrete rings. All this occurs underground, without noise and without disturbance to the traffic above. 

The TBMs excavate the tunnels in four pairs. Each pair of machines excavates two parallel tunnels. The first pair will excavate a tunnel west from the Galei Gil shaft in proximity to Arlozorov Station, the second pair will head east from Galei Gil Shaft. The third pair will enter at Herzl Shaft on Yehuda Halevy Street in Tel Aviv and excavate eastward, where they will meet up with the first pair at Carlebach Station. The fourth pair will enter at the Depot Shaft in Petach Tikva and will excavate westward, until they meet up with the second pair at Ben Gurion Station.
