HOCHTIEF is familiar with the alphabet in the Czech capital's underground. We were not only involved in the tunnels and stations of the A, B, C, and D subway lines. Where rail, streetcar, subway and car meet in one place, we helped relieve the pressure on surface road traffic with the construction of the Blanka Tunnel as part of the city ring road.
And sometimes we succeed in equalizing traffic on the second floor of the city. With the Negrelli Viaduct, we have reconstructed a structure that now enables quiet, comfortable rail traffic.
