26 August 2020

Continuing with the planning, the Nudo de Colmenar bridge, which supports the connecting branch between the M-607, towards Madrid, and the M-40, towards A-1, has been opened to traffic. 560.7 m, it was executed with curved concrete precast, variable depth, and constant depth; the structure is developed along 17 variable spans. The span that crosses the M-40 has a span of 56.2 m. The complexity of the work lies in its nature, it is a main communication hub in Madrid. The works were carried out in 10 months, of which only 6 were invested in the execution of the new board.
