Matanza Riachuelo River Project: Important milestone achieved

An important milestone has been achieved in Buenos Aires, for the remediation works of the Matanza Riachuelo River Project: two 60 m depth circular secant shafts have been completed with the use of a last generation hydromill. The shafts will provide enough space for the launch of the first of our two TBMs to dig more than 5km of tunnel under the Rio de La Plata River.
