One  of the key processes in the construction of Metro Line 2, the manufacture of 1,471 concrete "U" beams to support the 23 km track     was completed on Thursday, May 31.

The manufacturing process began in February 2016, at the Centenario Industrial Plant, which was also used on Line 1; and expanded to meet the demand for Line 2.

More than 150 workers were involved  in three shifts, 24 hours a day, to ready the beams  for the 23 kilometer line  and 16 stations. Over 19.5 kilometers is already built.

Over  92,673 cubic meters of concrete manufactured in the Centennial Plant,  was used.

Currently, 66 beams, which are in the yards of the plant, are waiting  to be moved. Their transfer and assembly will be completed by the end of July.

Each one is  between 20 and 30 meters long and over 5 meters wide weighing approximately 166 tons.
the  transfer and installation of the beams is done at night from 9:00 p.m. to  5:30 a.m., to minimize the impact on traffic in the area.
