On Tuesday, October 2^nd ,  the Metropolitan Public Company Metro de Quito informed the public that the TBM Luz de America reached the El Arbolito extraction shaft, completing the Quito Metro tunnel.

The TBM Luz de America began its work on April 5^th , 2017, from the Solanda Station, and passed through the Historical Center of Quito, without causing any damage to the city's heritage. The TBM ended its drive in the El Arbolito shaft after 9071 m and 6045 rings installed. Its average has been more than 1,500 m/1 month. Its twin sister, the TBM La Guaragua, has been averaging 1,100 m in the same period of time. The three TBMs La Guaragua, Luz de America and Carolina have now completed the 22km tunnel of the Quito Metro Line 1.  The TBM Luz de America will be dismantled and extracted from the shaft,  25 m deep and 28 m in diameter.

The progress of work for the project is at 75%. Click here and ec/19 for tunnelbuilder archive. Visit http://www.metrodequito.gob.ec . 42/18,
